You can use relative indexing with array.prototype.at:

const myArray = [1, 2, 3] console.log(myArray.at(-1)) // => 3 

You can use relative indexing with Array#at:

const myArray = [1, 2, 3] console.log(myArray.at(-1)) // => 3 

The Array.prototype.at proposal (stage 3) adds a method for relative indexing (MDN):

const myArray = [1, 2, 3] console.log(myArray.at(-1)) // => 3 

Another TC39 proposal, the 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 .at proposal is currently only implemented in pre-release versions of Firefox and Safari.

.lastItem is not supported in any browser, and the proposal’s champion currently considers withdrawing the proposal.

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

const myArray = [1, 2, 3] console.log(myArray.at(-1)) //=> 3
