Great video and some very valid points. Regarding the use of many optional properties, I somewhat agree. I think having 2-3 optional properties is manageable. However, for anything beyond that, I would recommend adding an options property to the User interface like so; options?: Partial; I think this approach is cleaner.

Yeap, I would also use partial.

Great points. I have read that some projects remove typescript from there projects and advocating that you don't need it. What do you think on this matter? Is it because of the strictness of typescript or the lag of knowledge of how to use typescript?

Doesn't make sense to me. Probably lack of knowledge and understanding how to write TS

Excellent points, people often don't use 10% of TS power in their projects. If you don't mind, what theme and font you're using? Looks amazing

Thanks for share this video. I have a question. If is bad practice use optional in interface, can I use for example name: string | null; instead of name?: string; Is it a good practice? Thanks

Optional is useful but you should not overuse it.
