Get the last item in an array

Question

Here is my JavaScript code so far:

var linkElement = document.getElementById(\"BackButton\");
var loc_array = document.location.href.split(\'/\');
var newT =         


        

Answer 1

const lastElement = myArray[myArray.length - 1];

This is the best options from performance point of view (~1000 times faster than arr.slice(-1)).
