1. What is a JavaScript developer?

First things first: What is a JavaScript developer? 

Together with HTML and CSS, JavaScript is one of the cornerstone technologies of the web. In very simplistic terms, it is a programming language used to add interactivity to a webpage. JavaScript is an integral part of web functionality, and is therefore supported across all web browsers and tools. 

JavaScript developers are, of course, experts in JavaScript—but what does that actually mean in terms of day-to-day tasks? 

JavaScript developers are responsible for implementing the frontend logic that defines how the visual elements of a web app behave. JavaScript developers typically work on the frontend, supported closely by backend developers and other frontend developers who specialize in markup and styling. You can learn all about the difference between frontend and backend development in this guide

To gain a better overview of what a career as a JavaScript developer entails, let’s consider some real-world job descriptions.

JavaScript developer job descriptions

A search on LinkedIn for JavaScript developer jobs in the United States returns over 7,000 results. To give you an idea of what a JavaScript developer actually does, we’ve taken a few snippets from some live job ads.

Our first example is a job ad posted by Apple, which describes the JavaScript developer role as follows:

In this role, you will have the opportunity to interact directly with our users and management to understand their requirements and impact their experience through the design and implementation of new features and customizations.

Under key qualifications, they ask for a deep understanding of frontend JavaScript development together with expertise in JavaScript libraries such as ReactJS and Redux. Desirable skills include experience with MySQL and scripting in Python and Perl. 

Our second example was posted by Grand Canyon Education, Inc. Here’s how they describe the JavaScript developer role:

2. Are JavaScript developers in demand?

A report by HackerRank, meanwhile, found that the global demand for JavaScript outweighs the expertise available on the market. According to the report, 48% of employers worldwide say they need JavaScript skills, yet only 42% of student developers say they are proficient in the language. 

So, if you plan on becoming a JavaScript expert, you can expect to be highly employable.
