JavaScript 101 (Day 2): Variables & Constants (var, let, const Explained)

Welcome back for Day 2 of the JavaScript 101 Course! 👋 After writing our first script yesterday, it's time to learn how to store and manage information in our code using Variables and Constants. This is a fundamental concept!

In this video (Day 2), we break down:
✅ Why variables are essential in programming.
✅ The "old school" way: Understanding `var` and why you'll still see it.
✅ The modern standard: Using `let` for values that might change.
✅ Unchanging values: Introducing `const` and why it's often preferred.
✅ Key differences explained simply: What makes `let` and `const` different from `var` (think scope!).

Understanding how and when to use `var`, `let`, and `const` is crucial for writing clean and effective JavaScript. Keep building your skills daily with this course!
