Introduction
What is JavaScript?
JavaScript is a high-level, dynamic programming language used to make websites interactive. It runs in the browser and on servers using Node.js.
How JavaScript Works
JavaScript runs in browsers using engines like V8. It uses a single-threaded call stack, event loop, and Web APIs to handle async tasks.
Setup Environment
Install Node.js, use VS Code, and set up a project folder with index.js to start coding in JavaScript.
