Variables, Data Types & Operators – JavaScript Tutorial for Beginners | Web Dev Series | JDCodebase

Welcome to JDCodebase! This Web Development Series covers HTML, CSS, JavaScript, and the MERN Stack in a complete beginner-friendly way. Every video explains concepts step by step with clear examples and practical demos, so you can confidently build real-world websites from scratch. In this tutorial, you will learn one of the most important foundations of JavaScript — Variables, Data Types, and Operators. These concepts are used in almost every JavaScript program, so understanding them clearly is extremely important for beginners. Many beginners feel confused about when to use var, let, or const, what data types JavaScript has, how operators work, and why === behaves differently from ==. In this video, all these concepts are explained slowly, clearly, and from absolute basics, assuming no prior JavaScript knowledge. You will learn how to store data using variables, understand primitive data types, use the typeof operator, and work with arithmetic, comparison, and logical operators. Everything is demonstrated with simple explanations and live coding examples in VS Code, so you not only understand the theory but also see how it works in real code. By the end of this video, you will have a strong JavaScript foundation, making it easy to move forward into logic building, conditions, loops, and real projects in the upcoming videos. 📌 What This Video Covers What variables are in JavaScript Difference between var, let, and const Scope and reassignment explained simply JavaScript primitive data types Number, string, boolean, undefined, and null Using the typeof operator Arithmetic operators (+ - * / %) Comparison operators (== vs ===) Logical operators (&& || !)
