JavaScript (JS) is a versatile, high-level, dynamically-typed programming language that enables interactive web pages and is essential for web development alongside HTML and CSS. Known for its ability to handle both client-side and server-side tasks, JavaScript is single-threaded, asynchronous, and uses a Just-In-Time (JIT) compiler for efficient execution. It allows developers to create dynamic features that enhance user experience, manipulate the DOM, interact with databases, and manage data. With the rise of Node.js, JavaScript has extended its reach to server-side applications, making it a critical tool for full-stack development.
To get started with JavaScript, you need a code editor and a web browser. We recommend using Visual Studio Code (VS Code) as your editor.

Add HTML structure:
- Add the following basic HTML structure to your
index.htmlfile:<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>JavaScript Course</title> </head> <body> <h1>Welcome to JavaScript!</h1> <script src="script.js"></script> </body> </html>
