Javascript Arrays

Array methods

let arr = ["a", "b", "c", "d", "e"];

slice()

I can define start parameter

slice(2) - second index of array is a start parameter

I can also define end parameter

slice(2,5) - second index of array is a start parameter, and fifth index of array is a end parameter

I can get last element of the array

slice(-2) - last two element

slice(1, -2) - start from second element without last two elements

splice()

arr.splice(2) - split from third element

arr.splice(-1) -
