JavaScript programming is a high-level programming language that is primarily used to create interactivity on websites. With the ability to control the behavior of page elements, JavaScript has become an indispensable tool for web developers.
What is JavaScript?
JavaScript is a client-side scripting language, meaning it runs in the end user's browser and not on the server. This allows web developers to create dynamic and highly interactive web pages. JavaScript can be used to perform mathematical operations, modify and manipulate HTML content, interact with the user through forms, and much more.
Initially developed as a way to add interactivity to static web pages, JavaScript has evolved into a full-fledged programming language with a wide range of functionality. Its simple syntax and seamless integration with HTML and CSS make it a popular choice among developers.
