It's always available for you. You can give it large tasks and it will distribute the work, push implementers forward, answer their questions, and only surface to you what's relevant.

You need to understand how unions distribute over conditional types to fully get why `Extract` works. Its definition can be somewhat cryptic:

yea ultimately unions and catalogs encode the same information so either option works! To extract a member of a discriminated union, I find that using the builtin Extract utility is the simplest, but I've noticed that the way Extract works isn't immediately intuitive to most people

And lastly, it makes writing generic function types so much easier! No need for pesky `Extract`s or `Exclude`s 🔥

Secondly, you can generate sub-unions super easily:

Firstly, having a catalog greatly decreases the number of type imports you need to make:

Pro tip: Don't write your #TypeScript union types by hand, use a Type Catalog instead! Why are Type Catalogs better? Find out in the thread 🧵 👇

A new TS-Pattern release is out! 👉 Prevent passing impossible patterns to `isMatching` when used with 2 parameters. 👉 `P.infer` behaves better when used in an argument position. just run `npm i ts-pattern@v5.6.0` in your project 😊 Release note: github.com/gvergnaud/ts...

Template Literal Types are awesome. If you concat `number` and a union of time units, you have a human readable AND type-safe way to provide time values! 👇
