How to solve it

In order to get the nth element of a given array, you have to know its index. An index describes the position of an element in a given array. Javascript arrays are zero-indexed. This means that the first element of an array has index 0. The second element has index 1 and so on.
const arr = [1,2,3,4,5]; // get first element console.log(arr[0]) // output: 1 // get last element console.log(arr[4]) // output: 5
