Comment

// A collection of the values 1, 2 and 3
const arr = [1, 2, 3]

// Each value is related to one another, in the sense that each is indexed in a position of the array
const indexOfTwo = arr.indexOf("a")
console.log(arr[indexOfTwo-1]) 
console.log(arr[indexOfTwo+1]) 

// We can perform many operations on the array, like pushing new values into it
arr.push(4)
console.log(arr)
