Generics, combined with conditional types can make for an incredibly powerful combination. When you look at things the right way, you can ask very useful questions about your types that allow you to build the precise API you want.
Just a tiny gotcha.
For the true beginners out there! We’ll put the files in a GitHub repo and connect it to Netlify to host it.
We can pass the mouse position from JavaScript to CSS and use it to make unusual and playful effects.
Got an old “modal” design? Now might be the time to upgrade it to a
It was a lovely day on the internet when someone asked how to CSS animated gradient text like ChatGPT’s “Searching the web” and promptly got an answer saying “Have you tried asking ChatGPT?

In a nutshell, we have Promises because we need callbacks. We need callbacks because JavaScript is single-threaded and can’t wait around for things. And so we dance.
