About JavaScript Programming

JavaScript is the programming language of the web. Originally designed for browser scripting, it has evolved into a versatile language used for frontend, backend, mobile, and desktop development.

With features like closures, prototypal inheritance, and first-class functions, JavaScript enables both functional and object-oriented programming paradigms.
