ts-toolbelt 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.

We have only scratched the surface of type manipulation in Typescript, if you want to get your mind blown, checkout community projects like ts-toolbelt and type-challenges.

Do you mean https://github.com/millsp/ts-toolbelt? You didn’t provide a link so I’m not sure which repo you’re referring to.

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.

Since posting this, some comments have made me aware that ts-toolbelt has this feature and a couple other really useful ones built in. So their source code could be worth skimming through to see how they did things.

I was curios enough to dug the definition along with a related types Narrowable and Cast

ts-toolbelt has a "Path" Type https://github.com/millsp/ts-toolbelt

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)
