Array Basics

👨‍💼 We need to store and access multiple values. Arrays let us keep an ordered list of items.

Creating an array:

const fruits = ['apple', 'banana', 'cherry']

Accessing elements (zero-indexed):

console.log(fruits[0]) // "apple" (first element)
console.log(fruits[1]) // "banana" (second element)
console.log(fruits[2]) // "cherry" (third element)

🐨 Open

index.js

and:

Create an array colors with at least 3 color names
Log the first element
Log the last element (hint: use colors.length - 1)
Change the second element to a different color
Log the entire array

💰 You can modify array elements:

fruits[1] = 'blueberry' // Changes "banana" to "blueberry"
