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 =

Personally I would upvote answer by kuporific / kritzikratzi. The array[array.length-1] method gets very ugly if you're working with nested arrays.

var array = [[1,2,3], [4,5,6], [7,8,9]]
​
array.slice(-1)[0]
​
//instead of 
​
array[array.length-1]
​
//Much easier to read with nested arrays
​
array.slice(-1)[0].slice(-1)[0]
​
//instead of
​
array[array.length-1][array[array.length-1].length-1]
