Array Basics

👨‍💼 Great! You can now create and access array elements.

🦉 Important notes about arrays:

Zero-indexed - The first element is at index 0, not 1
Dynamic size - Arrays can grow and shrink
Mixed types - Arrays can hold different types: [1, "hello", true] (though this is usually not recommended)

Getting the last element is a common pattern:

const last = array[array.length - 1]

// Or with modern JavaScript:
const last = array.at(-1) // Negative indices count from the end!

Even though we declared colors with const, we can still modify its contents. const only prevents reassigning the variable itself, not mutating the array.
