JavaScript Tutorial for Beginners to Advance : Understanding Primitive Data Types in JavaScript | Real-World Examples & Code

In this video, we dive deep into the world of primitive data types in JavaScript. I explain the different types—string, number, boolean, undefined, null, symbol, and bigint—with real-world examples and hands-on code to help you understand how each one works.

We'll also explore the typeof operator, which is essential for checking the data type of a value in JavaScript. Whether you're a beginner or looking to refresh your knowledge, this video will provide you with a solid foundation for working with primitive data types.

🔹 Topics Covered:

1. String: Represents textual data, like "Hello World".
2. Number: Represents both integer and floating-point numbers, like 42 or 3.14.
3. Boolean: Represents a true or false value, like true or false.
4. Undefined: Represents a variable that has been declared but not assigned a value.
5. Null: Represents the intentional absence of any object value.
6. Symbol: A unique and immutable data type often used as an identifier.
7. BigInt: Represents large integers beyond the limits of the Number type.
We'll also go through how to use the typeof operator to check data types in JavaScript.
