Working with arrays is an important ability in any programming language, particularly JavaScript, as we proceed to depend on exterior knowledge APIs. JavaScript has added strategies like discover and `findIndex not too long ago, however one syntax I like from languages like Python is retrieving values by unfavourable indexes.

Once you wish to get the worth of the final merchandise in an array, you find yourself with an archaic expression:

const arr = ["zero", "one", "two", "three"];
const final = arr[arr.length - 1];

You can use pop however that modifies the array. As an alternative you should use at and an index, even a unfavourable index, to retrieve values:

const arr = ["zero", "one", "two", "three"];
arr.at(-1); // "three"
arr.at(-2); // "two"
arr.at(0); // "zero"

at is a little or no recognized operate however helpful, if just for the shorthand syntax!
