A JavaScript Developer is an individual who is responsible for implementing the front-logic that outlines the behaviour of the visual element of an organisations web application.
A JavaScript Developer will also be responsible for connecting this with any services which reside on the back-end. They will work closely with back-end web developers, who will be responsible for server-side application logic, and also working with front-end web developers who specialise in styling.
JavaScript Developers are motivated individuals who combine the art of design with the art of programming. The main responsibilities of a JavaScript Developer are to implement visual elements and their behaviours with user interaction. They will work with back and front-end developers and will bridge the gap between the visual elements and server-side infrastructure. Additionally, they will develop new user-facing features, build reusable code and optimise applications for maximum speed and scalability.
