JavaScript

Matt Smith with wonderfully straightforward writing on why default parameters for functions are a good idea. I like the tip where you can still do it with an object-style param.

A satisfying little rant from Justin Fagnani: Stop Using CustomEvent.

Alex MacArthur shows us there are a lot of ways to break up long tasks in JavaScript. Seven ways, in this post. That’s a senior developer thing: knowing there are lots of different ways to do things all with different trade-offs. Depending on what you need to do, you can hone in on a solution.

If you want to try it out quick on a website, I wrapped it in a little injection JavaScript so you could paste it in the console wherever. […]

You want to hide an interactive element that you don’t need anymore after JavaScript loads/runs. Can you do it without a “flash” or layout shift?

Artem Zakharchenko: A great “aha” moment for me was when I realized you can use a single signal to remove multiple event listeners!
