JavaScript 101 (Day 3): Essential Data Types (String, Number, Boolean, Null, Undefined, Object)

It's Day 3 of the JavaScript 101 Course! 🎉 We've covered setting up and variables (`let`, `const`), now let's explore the different kinds of data we can actually store and work with – the fundamental JavaScript Data Types!

In this essential lesson (Day 3), we dive into:
✅ What exactly are Data Types and why are they crucial?
✅ `String`: How JavaScript handles text.
✅ `Number`: Working with all kinds of numbers (integers, decimals).
✅ `Boolean`: The simple power of `true` and `false`.
✅ `Null`: Representing the intentional absence of a value.
✅ `Undefined`: What JS means when something hasn't been assigned.
✅ `Object`: A first look at how JavaScript groups related data (more on this later!).

Understanding data types is key to writing code that works correctly, performing operations, and fixing bugs! We're building your core JS knowledge step-by-step, daily.
