TypeScript's type predicates are a powerful feature that improves type safety and makes code more reliable. They help confirm what a variable reall...

seems like a lot to type for small an achievement.
True, that's why I would recommend using assertion functions over type predicates.
It would be great if you can share some examples, thanks
Yes, but it can save you from a lot of issues
I think with TypeScript 5.5, you don't need the
issyntax anymore.See devblogs.microsoft.com/typescript/...
Doesn't this only apply to arrays?
nope luckily not
Thanks @alexanderop for sharing this
Incredibly useful! It’s super important to know this type validations to reuse types and avoid code duplication
Yeah, thanks for reading @algorodev
In fact if you want to check whether an object matches a type/interface, you could use the TypeBox library, that would make the whole process faster and less error-prone.
Schema validation with Zod is another helpful library. Makes your code robust and easy to develop: youtube.com/watch?v=V1HWH6FuTMc
Thanks, I will check it out.
Useful article!, Thank you for sharing.
Thanks @zaselalk
