JavaScript is a programming language that operates in web browsers. This web language gives web pages the capabilities of being interactive. JavaScript developers design web applications for clients, according to their instruction. They design animation, interactive images, drop-down menus, and embed sounds and music into a web page.

JavaScript developers can earn above average salaries, and this increases with experience and seniority. Industry projections indicate that this job will slowly decline due to outsourcing, industry, and technological advancements. Developers are expected to be multitalented in terms of the number of programming languages they use.
