Using Assertion to Convert Types in TypeScript

So ... if type assertion no longer exists after the compilation, what's the point of it? 🙂 I guess the main purpose is to avoid the compiler error (in case we want to use different types where they don't share the same variable)?

That's the basic idea. A good example would be if you want to create a variable that needs to be modified later, maybe with an ajax call...

interface Stuff { things: string; }

let stuff: Stuff = ({} as Stuff);

const ajax = "things";

stuff.things = ajax;
