Arrays & Array Methods
Arrays are ordered lists of data. They let you group multiple values into a single variable.
Creating and Accessing Arrays
Arrays are zero-indexed, meaning the first item is at position 0.
Modifying Arrays
You can add and remove items using built-in methods like push() (add to end) and pop() (remove from end).
Practice
Challenge 1: Create an array of three numbers, add a fourth number using push, then log the array.
