  I still haven't done enough TS to be much more than an "armchair theoretician" (typical KZread commenter) at this point... but, yeah, Phase 3 is best! ;)

  Based on this video, I created code that specifically changes the return type. I have the following union type and wanted to narrow down the type of the returned array depending on whether it's 'title' or 'body'. export type IndexMap = | { type: 'title'; keyword: string; target: Title } | { type: 'body'; keyword: string; target: Body } Therefore, I defined the return type as follows: function searchAt<T extends IndexMap['type']>( content: string ): Extract<IndexMap, { type: T }>['target'][] { return [] } If the type is 'title', it returns a Title[] and if it is 'body', it returns a Body[]. searchAt<'title'>('.....') returns Title[] searchAt<'body'>('....') returns Body[]

  People get into these problems for misusing enums, you want to do things that enums were not designed for. Enums are designed to represent a fixed set of related constants with descriptive names, which makes code more readable and maintainable.

  The way I read this now, this is similar to as const, but with as const you are narrowing the entire thing as a value while this will narrow the types for you only ? I saw also another comment that satisfies can be mixed with as const, what are actual use cases were combining both is desired?

  Best explanation out there of the why, and you answer the most common question, should I force ESM only? It's always depending on your users. Great video.

  If you like a minimal amount of dependencies, look into Fresh framework from Deno. You get EVERYTHING and ZERO build steps, it's absolutely calming.

  I guess your example is similiar to the usage of enum (?). are there any other example besides that?

  this isn't type safe at runtime. The server can return something you aren't expecting.

  Weird if they learnt js this shouldn’t be a problem I mean DOM nodes are anything from a tag to a text, and HTMLElements are html tags 🤲🏾

  Could you show a setup where the "package" uses React? I want to use React there to e.g. write reusable hooks that are then used in the apps.

  Add "jsx" to your tsconfig.json. That's it!

  I think "people doing database stuff" already have written try/finally blocks. And it seems a bit pointless to rewrite existing code which has no optimal performance value. So good for new/future development. Not very useful in existing projects. 2 cents.
