Hi,
I've just got bitten by
return getError().then(Promise.reject);
where `reject` threw an error that its `this` value was not a Promise
constructor.
Would it help to make the `C` constructor (in Promise.resolve, Promise.reject,
Promise.all, Promise.race algorithms) default to `Promise` when no `this` value
is supplied (throw only if it's there, but not an object and constructor
function)?
No, because as you suggested:
Or is this considered to be too error-prone with Promise subclassing, where
`.then(MyCustomPromise.reject)` would not work as expected (fail silently)?
Probably the best solution is an arrow:
return getError().then(r => Promise.reject(r));
