Values in an array are accessed as if they are in a numbered list
Arrays are zero based meaning the 1st “value” in an array is at position (index) 0, the 2nd element is at position 1, and so on
You access the value of an element in the array by passing the index of the item in square brackets
// declare a variable called chipmunks and use it to store
// an array of names
const chipmunks = ["Alvin", "Simon", "Theodore"]
// reference the first value in the array
// here we pass in a zero, since that represents the first
// element (value) in an array
const bandMember = chipmunks[0] //> the value stored in bandMember is "Alvin"
