Discussion on: Get last element of array in JavsScript

[Giorgi Kharshiladze]

I think you are missing one of the methods that was added not too long ago.
Array.prototype.at(). To get the last element in an array you can do myArr.at(-1).

Oh Yes !!! Thank You. This pretty usefull and easy

While it’s a cool new method, keep in mind that currently it’s not supported in Safari based devices.

In Safari Technology Preview you can activate it via Develop > Experimental Features

You can easily polyfill it:

if (![].at) {
  Array.prototype.at = function(pos) { return this.slice(pos, pos + 1)[0] }
}

This won't work with negative values.
