JavaScipt Tutorial

JavaScipt is a scripting language that is famously used in web development. It is a high-level, object-oriented, dynamic, and an interpreted language. It is a weakly typed language, meaning that variables do not have a type.

JavaScript is a member of the ECMAScript family of languages. ECMAScript is a family of specifications that define the syntax, semantics, and behavior of the JavaScript language.

JavaScript is a prototype-based language. It is a prototype-based language because it is designed to be used as a language for creating objects.

JavaScript was originally developed by Brenden Eich in 1995 and was first released in 1997. It was later open-sourced in 1998 and is maintained by the Netscape Foundation.
