seems like using regexes doesn't narrow types down either, e.g. const isAlphaNumeric = (input: string | undefined) => input !== undefined && /^[a-z0-9]+$/i.test(input) won't return `input is string` but just `boolean`

When Matt uploads a new video, we know it’s going to be a new useful knowledge. You’re awesome..❤

But a type guard is absent

What are advantages of namespaces over ComponentProps<T>? Or maybe it's just a curiosity?

so cool, I am new to know React.ComponentProps

Lol. The reason why `!!maybeNumber` doesn't work is that 0 is falsy 😅

I mean having tons of stuff in root_dir/dist seems a lot more preferable and sensible honestly. It seems a lot worse to have to chase down all the different build artifacts across node_modules every time you want to build from a clean slate. You kinda want your libs to be static and without artifacts. It's already a nightmare to debug dependency issues as it is.

Thank you for this I chose to use types even though I use c# on the backend But I use types cuz I was like fuck it, I’m not using inheritance 😆

Great release 👌 Indexed access type narrowing is also cool

I would like the video to explain what Turbo is and why I would need it.

I think your audio does not sync with the video

commonjs is here to stay

Congratulations on your book; I'm really looking forward to using the regular expression validation feature

cool feature, but it is still an inconvenience the name of namespace need to match the name of a component. That means you need to update both when refactoring code. Ideal behaviour would be giving the namespace a name and making it export the component by default i guess

I think the namespace should also be exported. Can’t get this to work without also exporting the namespace.

Does exporting like that interfere with ComponentProps<T> ?

how did you animate it?

there is a d.ts file generation issue that's been open in tsup for months that this might fix

I try to define explicit return types wherever applicable. It should be the default, just like all strict programming languages.

waiting for the book

Can we use it in a big project ? 🤔

7:30 does not work because !!0 is false and !!1 is true
