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.
