Boost Your JavaScript with JSDoc Typing
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.

My collection of helpful Utility Types :D
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.

Enforcing Localization through Types
Typescript doesn’t natively provide an Opaque type that we can use to define a string that has already been localized. If the data looks like a string, Typescript will consider it a string. We can however use utility types that simulate opaque types, like the Opaque definition in type-fest:

All JavaScript and TypeScript features of the last 3 years explained
Some folks have built whole SQL databases and DSL compilers in the TS type system. These tend to be toy projects with disclaimers not to use them. But the type system being Turing complete[0] (for better or worse), pretty much whatever you can imagine. This project[1] is one I actually return to frequently for practical ideas.
