— Also there is whole argument of type safety


Is it worth doing type safe js and lose time on development and also to learn to write type safe js in the first place for js developer ??

— You don't usually lose any time on development

— It's an implementation detail that has existing solutions

— Type safe js, depending on where it is, ranges from "nice to have" to "need to have"

— In a web app you can get away with unsafe code, but not serverside

— Serverside has lead to ring 0 kernel level remote code execution

— Any code that doesn't implement type safety in some form is generally vulnerable to attack over a much larger attack surface

— Other than that, it can help with debugging

— Yeah that makes sense

— Also some have said that writing type safe code helps you understand your code better

— Yeah, it does, as you set up expectations for all the data you're working with, which helps you construct a solid data model specification
