Gets the last item in the array

If you want to get the last item in the array, you will often write something like this:

Const arr = [1,2,3,4,5]; arr [arr.length-1] / / 5

In fact, we can also use the array's slice method to get the last element of the array:

Arr.slice (- 1)

When we set the parameter of the slice method to a negative value, we will intercept the array values from the back of the array, and if we want to intercept the last two values, the parameter can be passed in-2.
