Issue #454  (Array.at(), React, Git/CLI, Uncats)03/31/22

JavaScript's list of Array methods has quietly added a method called Array.prototype.at(). This relatively new feature, now supported in all modern browsers, is a replacement for using square bracket notation for accessing specific elements in an array.

For example, if you wanted to access the 5th element in an array, you would do the following using square bracket notation:

Using Array.at(), you simply pass in an integer representing the array's index that you want to access:

Your first reaction might be that this is basically the same as the square bracket syntax, but a few more characters. But there is at least one extra perk with Array.at(): You can use negative values to access elements by index starting from the end of the array. Here's some code to show how this works:

Try it on CodePen

You can see that I twice accessed the last element in the array using a value of -1. The second time I did this was after I added an element to the end of the array.

This is much nicer than using square bracket notation with something like myArray[myArray.length - 1] or some other convoluted technique. The code above is much cleaner and easier to understand as long as you know what a negative value does in this context.

If you don't pass any value into Array.at(), it defaults to an index of 0. The method returns the element at the specified index and the original array is not affected. If the index doesn't exist, the method returns undefined.

Before I Go...

In case you didn't know, Pantone 448 C, with hex value #4A412A, is apparently the ugliest color in the world. Is it uglier than that bathroom in the Tweet though? It's close.
