alt Hacker NewsHundreds of unit tests replace a type.
Start using properties and it is in the thousands.
Most code should be typed. Python is great for prototypes, but once the prototype gels, you need types.

A unit test is a functional assertion. A type is a semantic construct that can provide that, but it provides a lot more.
As a trivial example, if I create a type alias from “string” to “foobarId,” I now (assuming a compliant language) can prevent code that consumes foobarIds from accidentally consuming a string.
I've always hated Python. Could never enjoy it at all. Pretty much the same poor DX as PHP, Javascript, Ruby, etc.
Finally set up neovim with pyright; use types on every single fucking thing, and now I love Python[1].
Can't wait to see TC39 become a reality (learned about it just this past week on HN, actually). Maybe I'll enjoy Javascript too.
