Introduction to JavaScript – JavaScript Tutorial for Beginners | Web Development Series | JDCodebase

Welcome to JDCodebase!
This Web Development Series covers HTML, CSS, JavaScript, and the MERN Stack in a complete beginner-friendly way. Each video explains concepts step by step with practical demos, so you can confidently build real-world websites from scratch.

In this tutorial, you will learn JavaScript from the very basics. JavaScript is the programming language that makes websites interactive and dynamic. It allows you to respond to user actions, update content without reloading the page, validate forms, and build real functionality on top of HTML and CSS.

Many beginners get confused about what JavaScript actually does, where it runs, and how browsers execute JavaScript code. In this video, all these fundamentals are explained clearly and slowly, assuming no prior JavaScript knowledge. Everything is taught in a simple and practical way, with live examples and basic coding in VS Code.

You will learn how JavaScript works inside the browser, what JavaScript engines like V8 are, where JavaScript can run (browser and server), and the correct ways to add JavaScript to a webpage. You will also learn how to use the browser console, which is one of the most important tools for JavaScript developers.

By the end of this video, you will have a strong foundation in JavaScript, so you can confidently move on to variables, logic, and real projects in the next videos.
