I was thinking about this the other day i would love for TS flag that would turn an interface into an assert const shout = (message: string) => console.log(message) into something like const assert = require('assert'); const shout = (message) => { assert(typeof message === "string"); console.log(message); } of course this doesn't work for more complicated types
