What is JavaScript ?

JavaScript is a single-threaded, synchronous programming and scripting language widely used in web development. It plays a crucial role in both front-end and back-end development, enabling dynamic and interactive user experiences. Unlike compiled languages, JavaScript is interpreted through web browsers, making it highly accessible and versatile. It is a loosely typed (or weakly typed) language, meaning variable types are determined at runtime.

JavaScript enhances web page interactivity by allowing dynamic content updates, handling button clicks, setting timed updates, and more.
