Issue #370  (JS Tricks, Testing, Media, Uncats)08/20/20

This past week I came across a YouTube video by someone named Aaron Jack called 21 LIFE CHANGING JavaScript tricks that you'll definitely want to check out if you'd like to pick up a nice collection of JavaScript tips and suggestions. Some of the tips are fairly basic, but many are not so well known.

Aaron has over 170,000 subscribers on his channel but I had not heard of him until I'd seen that video. Based on the quality of the video, he's worth a subscribe. The video is well edited and pretty easy to follow, though he does move pretty quickly through the tips (21 tips in about the same number of minutes).

So for this week's "tip" I think that video will suffice to keep your quick tip hunger satiated for a while!

Do you like JavaScript tips? I've collected together tons of similar tips in my JS/DOM E-Books Bundle.

Now on to this week's tools!
