that won't work. they still have to await it because the method is async.

u can try it both ways and see.

the caller has to use await, but r.json() is a promise. if you don't await that then the caller needs to do:

const res = await postJson(); <- this is a promise, not the json
const jsonRes = await res;

instead of just

const jsonRes = await postJson();

that's not how it works. did you try it?
