👨‍💼 You've created your first functions! Notice how you can call them multiple times - that's the power of reusability.

🦉 Function declarations are "hoisted" in JavaScript, meaning you can call them before they appear in the code:

greet() // This works!

function greet() {
	console.log('Hello!')
}

This is different from other ways of defining functions (like function expressions), which we'll see later.

Good function names are verbs that describe what the function does: greet, calculateTotal, validateEmail, fetchUser.
