JavaScript is a lightweight programming language that comes with first-class functions. In addition to being used for web pages, it is also commonly used for non-browser environments such as NodeJS, Apache DB, etc.
JavaScript is a popular multi-paradigm language, for its ability to support object-oriented, imperative, and functional programming styles. Another aspect of JavaScript that often goes hand-in-hand with it is jQuery. jQuery is nothing but a free cross-platform JavaScript library that simplifies the process of client-side scripting.
