Sarah Drasner shared her awesome Array Explorer tool on Twitter the other day. It’s design is pretty simple, and yet a powerful way to learn JavaScript arrays. What you do is pick a couple options from drop-down lists to find the right array method you need for a project.

I still find arrays challenging and yet learning how to work with them in JavaScript is so important. If you’re still figuring this stuff out, definitely take a look at Array Explorer, bookmark it, and use it.

Sarah even made the code for Array Explorer available on GitHub so you can see how she put it together too.
