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

Getting the last item of an array can be achieved by using the slice method with negative values.

You can read more about it here at the bottom.

var fileName = loc_array.slice(-1)[0];
if(fileName.toLowerCase() == "index.html")
{
  //your code...
}

Using pop() will change your array, which is not always a good idea.
