Introduction to JavaScript

What is JavaScript?

JavaScript is a high-level, interpreted programming language primarily known for its role in web development. Initially designed to add interactivity to web pages, JavaScript has evolved into a versatile language used across server and client-side applications. It’s a core technology of the web, working alongside HTML and CSS to create dynamic, interactive experiences on browsers.

History and Evolution of JavaScript

JavaScript was developed by Brendan Eich at Netscape in 1995 under the name "Mocha," later renamed "JavaScript" to align with the then-popular Java language. Initially a simple scripting language, JavaScript has grown immensely in capability with the development of frameworks and standards like ECMAScript (ES6) and Node.js, transforming it into a powerful tool for web and application development. JavaScript is now used not only in browsers but also on servers and IoT devices, making it one of the most widely-used languages.
