JavaScript is a multi-paradigm programming language well-suited for event-driven, functional and imperative programming styles. Initially used exclusively in client-side (front-end) development, it has evolved to now cover the server-side (back-end) software building. JS frameworks and libraries, like Angular, React, Vue, Node, are widely used by web developers as they provide generic programming functionality with the ability to selectively change it by means of adding hand-written custom code. JS frameworks are also viewed as more adaptable for website application design and development of device-responsive applications.
