With technology developing as rapidly as it is today, many new and different uses for JavaScript are developed. This in turn also means that JavaScript Jobs are in demand.
With the help of Leftronic you will be able to find out just how important JavaScript Developer jobs are.
Kicking things off with the basics…
The Rise of JavaScript
Let’s round out some of the most important events in the history of JavaScript:
- 1993 – Mosaic web browser released as the first web browser with graphical user interface.
- 1994 – Netscape Navigator, a more polished browser, released and quickly becomes the most used browser.
- 1995 – Netscape adds a scripting language to Navigator in order to pursue dynamic behavior.
- 1995 – Brendan Eich devises a new language, with similar syntax like Java, dubbed LiveScript. Three months later the language was renamed to JavaScript.
- 1995 – Microsoft debuts its Internet Explorer and reverse engineers the Navigator Interpreter to create JScript.
- 1996 – Netscape officially submits JavaScript to ECMA International.
- 1997 – ECMAScript language specifications officially released in June and mark an important point in JavaScript history.
- 1998 – ECMAScript 2 released.
- 1999 – ECMAScript 3 released.
- 2000 – Internet Exploder’s market share reaches 95% while JScript becomes the de facto standard for client-side scripting on the web.
- 2005 – Mozilla joined ECMA International and started working on ECMAScript for XML.
- 2008 – Google releases Chrome browser wtih V8 JavaScript.
- 2016 – ECMAScript 6 published.
But we can’t go on without first discussing a very important discrepancy when it comes to JavaScript. The biggest question novice users ask is about the…
Difference Between Java and JavaScript
The choice of choosing JavaScript for the name of this programming language has caused a lot of confusion. People had the impression that JavaScript was a spin-off of Java. But the reality is not even close.
Similarities between Java and JavaScript do exist – for example, the JavaScript syntax is used, the name, and the fact that they are both used for web applications.
But the two languages also have notable differences. Particularly when it comes to design.
Java is an object-orientated programming language that allows you to create compiled programs that are able to run on almost every platform.
Java vs JavaScript
Java | JavaScript |
Java is a strongly typed language where a variable must be declared first to use in a program. | JavaScript is a weakly typed language that has relaxed rules and syntax. |
Java is an object-oriented programming language. | JavaScript is an object-based scripting language. |
Objects in Java are class-based. | Objects in JavaScript are prototype-based. |
Java applications are able to run in any browser or virtual machine. | JavaScript code can only run on a browser where JavaScript is developed for browser only. |
Java has the “.Java” file extensions and translates its source code into bytecodes, which is executed by JMV. | JavaScript has a “.js” file extension and is interpreted but not compiled. Actually, every browser has JavaScript interpreter so they can execute JS code. |
Java is a standalone language. | JavaScript is contained within a web page and integrates within the HTML content. |
Java has a thread-based approach to concurrency. | JavaScript has an event-based approach to concurrency. |
Additionally, besides all the differences that JavaScript function has opposed to Java, one of the more important ones is in terms of memory. Java requires much more memory than JavaScript, which allows it to be used in web pages.
Bottom line, both Java and JavaScript are programming languages useful on their own. Both of them have advantages over each other. You can’t really say that one is radically better than the other. Programmers use both languages for various needs and it would be immensely better for a person to know both.
But we already mentioned that JavaScript is a multi-paradigm language. For those of you who want to know more about it, we decided to add something more about it.
What Are JavaScript Programming Paradigms?
In order to explain it, we need to start by defining what a paradigm is.
Modern programming languages used today are usually divided into two categories, imperative (also called procedural) and declarative (also referred to as functional).
Examples of imperative programming paradigms are object-oriented programming, parallel processing, and procedural programming.
As for declarative programming paradigms, they include functional programming, database processing, and logic programming.
JavaScript paradigm supports both object-oriented programming, prototypal inheritance, and functional programming. Originally, Java was the best example of pure object-oriented programming but the 2018 update added some additional functions. On the other hand, SQL jobs are the best example of pure declarative programming.
Characteristics of Declarative Programming
- You declare what you want to happen.
- Data is often considered immutable values (not changeable).
- There are no loops or conditional statements.
Characteristics of Imperative Programming
- You specify exactly how something needs to be done.
- Inheritance is commonplace and usually used as reusable, clean code to help other developers.
- Data is often considered mutable variables (changeable).
- JavaScript array allows us to mix both types of coding into one project.
But which one of them is better? Traditionally speaking, Imperative programming is viewed as more enterprise-ready and reusable. Even though large OOP apps can have problems when it comes to nested inheritance of objects.
Now when we have all the technical terms out of the way for novice applicants, we can go to the part which will help you land a job. Both experienced and beginner applicants should try as it could lead to a very lucrative career.
JavaScript Job Description
A JavaScript developer is responsible for making and completing the design of a software or application by utilizing the Java programming language. They work with websites, application programming interfaces, and front-ends web development. Additionally, their job is to perform code analysis and improve style and usability.
JavaScript developers are in most cases supported by back-end developers, who are responsible for server-side application logic. Developers usually work in tandem with front-end web developers who are proficient in markup and styling.
Explaining JavaScript jobs in layman’s terms – a front-end developer will combine HTML, CSS, and JavaScript to create everything that the user is able to see on the interface. This involves all the front-end features like the buttons, the drop-down menu, fonts, etc. A back-end developer will then handle the part of retrieving the data, how it is being stored and manipulated on the server. A JavaScript developer basically takes the front-end part to the next level.
On the front-end, this requires more in-depth knowledge of JavaScript, while on the back-end it relates to some server-side technologies.
However, all JavaScript developer jobs come with different responsibilities. They may include the following:
- Develop new user-facing features.
- Ensure technical feasibility of UI/UX design.
- Build reusable code and libraries.
- Optimize applications for maximum speed and scalability.
- Make sure that all user input is validated before being submitted to back-end services.
- Enhance performance of the main front-end website.
- Analyze code, system risk, requirements, and software reliability.
- Collaborate with both front-end and back-end developers.
- Performance tuning, automation, balancing, improvement, and usability.
- Develop specifications and designs for complex applications.
But what does it take to become a JavaScript developer?
JavaScript Jobs Requirements
Being hired as a JavaScript developer will require you to have a combination of various things.
Some basic requirements include:
- Degree in Computer Science, MIS, Engineering or a related field.
- Extensive knowledge and understanding of JavaScript.
- Experience with JavaScript libraries.
- Experience in front-end tools.
- Proficiency in browser rendering behavior and performance.
- Good understanding of web markup.
Still, each individual job position offered by a certain employee will have different requirements. But in order to apply for any JavaScript jobs openings one has to have a combination of a few most important things.
They will include the necessary work experience, specific education, a certain certification, and a required set of skills.
Experience
Experience levels different from company to company. It also depends on the seniority level of the position. There you will see how serious the firm is and what level of devotion they demand from their workers.
Basically, most of them are looking for employers who have at least 2 years of experience. Entry-level JavaScript jobs may come with even less than that. Some employers will even accept work experience in some similar fields.
Education
When it comes to education, requirements greatly vary. Actually most employers are really concerned about the skills one is able to display. Thus being hired with an Associate’s degree is quite possible. Having a Bachelor’s degree could be an advantage if there is a tie between some applicants.
Companies usually look for workers that have a diploma in computer science, information system or math. But there are cases with workers that have a non-computer related degree, like finance or accounting for instance.
Interestingly, but a diverse background can sometimes be attractive to potential employers.
JavaScript Certification
A JavaScript certificate can make a great difference when one applies for a job. Most people still think that you have to be able to show that you can do something instead of owning a piece of paper. While that is partially true, this type of paper really does make a difference.
Most future employees are prompted to obtain one as it could give them an edge when going against other applicants.
Many people ask – “Is there a JavaScript certification?”
Sure.
But a better question would be – Which one to obtain?

JavaScript Job Skills
A JavaScript developer will need to possess a specific set of skills needed for the job. Actually, all developers need to have similar skills. The main difference, in this case, is going to be just the added ones that are specifically connected to JavaScript. Thus we start with…
Soft Skills
Keeping up with the Industry
The world and especially the IT industry is developing at a fast pace. Thus a developer of any kind needs to focus on following the latest trends in the industry. New programs, coding languages, devices, and applications are being released on a daily basis. Being familiar with most of them will allow you to excel at your job.
Knowing the JavaScript fundamentals will get you places in the beginning. But if you really want to advance at this position, you need to be able to inform yourself properly about the newest emerging trends related to JavaScript and technology all-together.
Knowledge of Different Platforms and Browsers
This part directly correlates with the aforementioned one. Namely, new technologies need to be incorporated across different platforms and browsers. A good developer will need to adapt them and make everything work seamlessly no matter the program at hand.
Thus being knowledgeable about various platforms and browsers will help even a JR web developer adapt quicker.
Excellent Communication Skills
Working in a team does not mean idly sitting at your computer and doing your job. It requires day-to-day collaboration. Developers particularly need to work together and also with other members of the team or company in order to finish their tasks.
Communication skills are probably not the first thing that comes to mind in regards to JavaScript development. But it is always one of the JavaScript interview questions. Do not take this skill lightly.
Technical Skills
HTML / CSS Frameworks
As part of front-end development that JavaScript experts need to incorporate in their work, advanced knowledge of HTML and CSS frameworks is necessary. However, the basics are not going to cut it. Developers are going to need to know about the latest ones, like HTML5 and CSS3 in order to perform their jobs.
This skill is particularly going to be needed when it comes to combining with different frameworks. Bootstraps and other frameworks like LESS and SASS are also going to be needed for HTML CSS jobs as well.
JQuery
We already know that JavaScript is what holds the functional and dynamic elements of HTML and CSS together. Using it primarily is good but being capable of using a library such as JQuery will make certain tasks much more effective.
Some people say that using JQuery may cause some conflicts to occur. But generally speaking, the advantages outweigh the disadvantages. A library collection of all the plugins, shortcuts and extensions that allows certain tasks to be finished faster.
React & Redux
React and Redux is going to be really important for JavaScript jobs in 2020.
React started gaining attention in 2015 when AngularJS frameworks started having issues. At that point, React started getting more attention in the JavaScript development community.
So after the switch was made to React, Redux became a much easier way of testing out applications. It greatly helped in diminishing bugs in future apps.
Node & Express
Even though a JavaScript programmer mostly deals with the frontend, their role in the backend is growing in recent times. Therefore, knowing about Node and Express is more than helpful. These two frameworks are very popular when it comes to using JavaScript at the backend.
If you really want to complete your JavaScript skills, you should add either one of the two to your repertoire of skills.
Meteor
Meteor has been gaining traction among JavaScript developers in recent times. Possessing knowledge about Meteor for any JR web developer jobs is really positive. Mainly because Meteor is a lightweight and easy to use framework, especially for a beginner.
People who are just starting out as JavaScript developers or people who want to prototype easily should consider learning about this framework.
There you go!
Make sure that you tick off all the boxes when it comes to experience, education, certification and skills and you will be good to go for your next job application.
But now we discuss the thing that you will get in return for being hired successfully.
We are of course talking about your potential earnings!

We still do have some more interesting facts for you to help you understand the importance of JavaScript today.
Why is JavaScript the Most Used Programming Language?
At its most basic level, programming languages are used to instruct computers how to perform tasks. Since all of us use computers, the importance of these programming languages has risen to enormous magnitudes.
This prompts more and more people to learn how this is actually done. Consequently, it creates a need for developers in the industry who are good at using these programs.
Programming knowledge has already become an important skill today besides JavaScript developers we also need PHP developers, people good at Python, SQL, etc.
According to Statista, JavaScript has emerged as one of the most used programming languages in 2019.
The research shows the following results in usage percentage:
- JavaScript – 67.8%
- HTML/CSS – 63.5%
- SQL – 54.4%
- Python – 41.7%
- Java – 41.1%
As you can see, around 68% of surveyed people said that they used JavaScript as their primary programming language.
This furthermore opens the need for more jobs where JavaScript can be used.
What Jobs use JavaScript?
JavaScript is a scripting language whose main purpose is adding and controlling dynamic content to websites. But this all needs to be combined with mark-up languages like HTML and CSS and help browsers display websites. That said, there are a lot of different things that one can do with their JavaScript knowledge.
One does not necessarily need to become a JavaScript developer. There are a bunch of CSS jobs and other career options in front of you that you can pursue.
Like for instance…
- Frontend Developer: Building the visual part of the website that faces the user.
- Web Application Developer: Creating web-based software applications.
- UX Designer: Studying and researching how people use a site.
- Web Designer: Designing how a website looks and works.
- UI Designer: Creating the interface that the user needs to manipulate.
- FullStack Developer: Designing the front-end and the back-end of a site is what a full stack engineer needs to do.
- DevOps Engineer: Setting server software, version control, deployment, and testing servers.
Top Uses of JavaScript
Being that JavaScript is one of the most used languages in the world there are many ways one can utilize it.
- Web Development: JavaScript is a client scripting language that can be used in making web pages.
- Web Applications: With the help of JavaScript, browser technology has improved and allowed the creation of robust web applications.
- Presentations: JavaScript offers a place where one can create presentations as a website.
- Server Applications: One of the JavaScript resources is a built-in Node JS that comes added on Chrome’s JavaScript runtime. It allows you to rapidly build scalable applications.

- Games: A combination of JavaScript and HTML5 is used in modern game development.
- Art: Using HTML5 in JavaScript drawing graphics is now a lot easier on web pages.
- Smartwatch Applications: JavaScript provides a library Pebble JS that is used in smartwatch applications.
- Mobile Applications: JavaScript allows building applications without web contexts. Since mobile phones mostly use Android’s or Apple’s programming language, it should be possible to write it once and use it on both platforms.
JavaScript Basics
Let’s start with the obvious:
What is JavaScript?
JavaScript is an interpreted programming language that allows a person to implement complex features on web pages. The idea is that it is able to create interactive web pages. So any time you see a page moving or doing something after you manipulate it, this is JavaScript at work.
Alongside HTML and CSS, JavaScript is responsible for the majority that you see on the World Wide Web.
JavaScript is characterized by having curly-bracket syntax, prototype-based object-orientation, dynamic typing, and first-class functions.
JavaScript is easy to learn and can allow you to make beginner JavaScript projects without any fuss, but it still requires time and effort to master.
The basic idea is always never giving up. But in order to set you straight, here are some fundamental tips that you can follow to reach success.
Learn the Basics
Start by studying the basics. It does sound time-consuming but it is very useful in understanding all the ins and outs that will later become quite useful. Doing some simple JavaScript projects for starters will help you in the long run.
Functional Programming
Making pure and simple code allows it to be refactored when needed. An agile environment will oftentimes force change. A clean approach to your code will allow you to refactor things very quickly.
Pick the Right Tool for the Given Problem
Don’t rush and do not jump to conclusions! Solving a certain problem takes time. Thinking carefully about it will help you solve it better. With practice, a person will be able to understand the best ways of dealing with certain situations. Acquiring experience allows you to understand which tool to use in a specific type of situation.
Try Open Source
Something that your Google JavaScript certification does not tell you is to utilize open source. This is a great starting point for your career. It allows you to solve any initial domain problems that might occur. Being a part of a community is an excellent opportunity for a young developer to learn all the curves that the job can come with.
Be Proactive
Certain people don’t really like to get involved in the development of the entire project. They mostly focus on certain features only. This can limit your understanding of the whole problem. Thus proactivity will allow you to know more about a certain problem and how to apply solutions to it.
Communication
This is definitely one of the most important parts of all JavaScript jobs. Working in a team is necessary. Groups of people are able to build better and bigger things as opposed to individuals. Thus being able to collaborate freely with others will reap success. Even engaging with others about something that is not related to the development will allow you to acquire something. Don’t be afraid to do it and be sure to try it.
So if you are still asking yourself – How do I become a JavaScript Pro? This is the way to do it. The road is slow and it does take time. But if you apply yourself and be patient it will come to you.
Freelancing
Besides the regular way of acquiring a job related to JavaScript, there is always the other way around. You don’t always have to work in an office in order to do a good job. Some people perform better from home. So freelance JavaScript jobs are a perfect way to start your career. It will allow you to master the language as a fresher. Furthermore, you will be able to develop and become much better at it through the course of time.
The popular platform for this type of work, Freelancer, currently lists 1,200 projects listed. The pay different based on the project. It can go as low as $20 or as high as $1,000. It still depends on your skills.
Remote JavaScript jobs are also a good way to start your career. Working on a project remotely from your home allows you the ease and comfort that you can only have in the warmth of your home. Most people do prefer working this way as opposed to being cooked up in an office. One can work remotely on a single project or you can even get hired as a full-time worker in a firm. You still have to do the same work as you would in an office with the only difference being doing it from anywhere with a stable internet connection.
After acquiring the necessary skills for the job, think about JavaScript jobs from home! It provides a lot of room for development. And if you are good and diligent enough you will one day be able to get a full-time job at a big firm.
To Conclude
The modern way of browsing the internet would not be possible without the use of JavaScript.
All the cool looking and interactive web pages we visit on a daily basis would be dull and static. JavaScript is what makes the internet go round.
Even though there is a heap of other programming languages in existence today, people are still relying on JavaScript.
If you are still asking yourself – Can you get a job with just JavaScript?
The answer is YES!
The need for JavaScript experts is not going to decline any time soon. With the creation of new applications and websites, the need is only going to be greater. Additionally, new uses of JavaScript are popping out as people are finding new and creative ways of utilizing it.
Therefore, JavaScript jobs are a very lucrative way of embarking on a new career.
