Link: Real-world uses of TypeScript’s utility types - Piccalilli
I have a bit of love-hate relationship with TypeScript, but there are parts of the typescript Type system that I really like. This article from Piccalilli is a great introduction to TypeScript's utility types (which is one of the areas I like, even though it is a bit complex)
Utility types are types that modify other types. You can think of them as functions, but they operate on types instead of values. It’s mind bending at first — especially if you’re coming from languages that don’t have anything similar — but we’re going to walk through a load of examples to see how they work.
Mind-bending indeed.
One of my favorite types that I've made is here in Breadboard. It could take a function and return a proxy for that function that had the same calling parameters.... I think... I'm not sure, I wrote it a while ago... heh, that's the "hate" part of the relationship. :D
I lead the Chrome Developer Relations team at Google.
We want people to have the best experience possible on the web without having to install a native app or produce content in a walled garden.
Our team tries to make it easier for developers to build on the web by supporting every Chrome release, creating great content to support developers on web.dev, contributing to MDN, helping to improve browser compatibility, and some of the best developer tools like Lighthouse, Workbox, Squoosh to name just a few.
I love to learn about what you are building, and how I can help with Chrome or Web development in general, so if you want to chat with me directly, please feel free to book a consultation.
I'm trialing a newsletter, you can subscribe below (thank you!)
