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

I generally use underscorejs, with it you can just do

if (_.last(loc_array) === 'index.html'){
  etc...
}

For me that is more semantic than loc_array.slice(-1)[0]
