utility-types VS type-challenges

There are a bunch of awesome type utility libraries that may boost your works on types, like ts-toolbelt, utility-types, SimplyTyped, etc., which you can already use.

With these powerful features, you can create dynamic and expressive types. One last thing I want to mention before moving on, is that you can install libraries with which you can add more types to your project like type-fest or utility-types. These libraries contain a lot of useful types that you can use in your project.

I am guessing that since it does not exists as an built in type, in utility-types, or in ts-toolbelt that it currently isn't possible.

You can also check out projects like https://github.com/piotrwitek/utility-types which also bring a lot of value and easy to use.

There is something similar here: https://github.com/piotrwitek/utility-types, but it hasn't been updated since TS 3.7 and there is a LOT more that can be done with TypeScript since 3.7. Mainly variadic tuples and template literal types.

For those who want to improve their type level skills, I highly recommend this repository for learning by doing: https://github.com/type-challenges/type-challenges.

I'm very like typescript and I always try to learn something interesting there. I thought that it is impossible to know the length of the string in typescript, but I was wrong. Today during solving typescript challenge I found a way to do it. If you don't know about typescript challenges, you can read about it here, it is a very interesting project, and I highly recommend you to try it, if you, like me, obsessed with typescript.

For those wonder why you don’t need a CS degree, I invite you to solve the type problems here https://github.com/type-challenges/type-challenges. No degree needed and if you can solve those problems with ease (as really understand the problems), you can work on any problems in any business.

It's not really a major usage but I think it would be cool to see if a coding model could be fine-tuned to take in a prompt of instructions and output a valid Typescript type solution (like in https://github.com/type-challenges/type-challenges)
