Write Solid Code with Branded Types in TypeScript 🛡️

[@kasir-barati]

God tier video.

[@gambonny]

Very informative. Thanks.

[@TypeScriptTV]

Happy that you like it! Have you seen my video about generators? kzbin.info/www/bejne/eqi1hGmcYrqtl6M

Bypassing of type guard check for value of undefined seems to be not related to additional check of typeof input === "number". undefined is not a number but it is not 0 neither. what for is typeof input === "number" introduced there?

[@TypeScriptTV]

Your concern is valid. The `typeof number` check at 16:06 is unnecessary: typescript.tv/hands-on/understanding-branded-types-in-typescript/#using-assertion-functions-with-branded-types Thanks for the hint! Benny

[@sakarsr]

Thank you for making this video on the branded type and its issues with the assertion. Putting two or more assertive conditions-one for notzero and another for number-is not possible. Alternatively, is there a way we could make different kinds of barnded nests?

[@TypeScriptTV]

Hey, for such complex validations I recommend to use a schema validator like Zod: typescript.tv/hands-on/use-typescript-generators-for-cleaner-programming/#response-schema-definition

[@sakarsr]

@@TypeScriptTV I do utilize Zod for my development, yes.

can you make video, using typescript in react?

[@TypeScriptTV]

It's a great topic and there is already an excellent course for it on Udemy: www.udemy.com/course/react-typescript-the-practical-guide/

how to complicate a simple problem 101

[@TypeScriptTV]

It's called Software Architecture. 🙂

[@justAbeautifulSoul409]

​@@TypeScriptTV I know. By the way, I was referring to the problem you were solving; it was a simple one and didn't require all those lines of code to handle. Are you aware that many projects don't use TypeScript but still follow software architecture?

[@TypeScriptTV]

@@justAbeautifulSoul409 I am aware of this but I like to use small code examples to show the technique so my viewers don't get lost in complex business logic.
