JavaScript is a programming language created in 1995 by Brenden Eich. Initially, it was only supported by Netscape Browser, but later they decided to release a standard known as ECMA specification to let other browsers implement and provide engines to execute JavaScript on their browsers. The reason for providing the standard is to have the complete specification details for the party to follow and provide consistent behavior.

Earlier it was only targeted to execute on browsers and perform client-side operations that work with HTML pages and provide features such as manipulating DOM elements and defining event handlers and other functionalities. Later, and in recent years, it has become a powerful language and not only bounded to the client-side operations. With Node.js, we can use JavaScript on the server side and there are various modules and plugins provided by Node to perform I/O operations, server-side events, and more.
