JavaScript

JavaScript is a programming language used to develop interactive and dynamic web pages. It was developed by Netscape Communications Corporation (now Mozilla Corporation) and is one of the most widely used languages in web development.

JavaScript allows programmers to add interactivity, animations, dynamic content changes, and many other features to web pages. This means that pages can respond to user actions such as button clicks, form entry, and mouse movement.

It is sometimes confused with the Java programming language, but they are two different languages. Java is a full-fledged object-oriented programming language, while JavaScript is a scripting language mainly used in browsers to manipulate web content.

Today, JavaScript is widely used not only in web development, but also in many other contexts, such as server applications (Node.js), mobile applications, and even the Internet of Things (IoT).
