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 =

Not implemented yet!

The new TC39 Array.prototype.lastItem proposal (stage 1) adds a getter that returns the last item in an array:

const myArray = [1, 2, 3]

console.log(myArray.lastItem)
//=> 3

The Array.prototype.item proposal (stage 3) adds a different API:

const myArray = [1, 2, 3]

console.log(myArray.item(-1))
//=> 3
