Courses Plus Student 1,566 PointsUsing `return` keyword with `resolve` and `reject` callbacks
Since resolve
and reject
are essentially callbacks, could we use return resolve(data);
instead of just resolve(data);
as we did before within callbacks topic. The same applies to the reject
callback. Thanks in advance. Guil Hernandez

47,913 PointsYou definitely can use the return
keyword before those calls if you'd like. Since you're right that reject
and resolve
are just callbacks in the same way that the previous implementation had a callback, in this specific instance, it won't do anything than what the original callback version was doing. It didn't really do anything in either case, because the calls to callback
, reject
, and resolve
were all at the end of their functions, anyway. Be a little bit careful when you do this, though, because the return
keyword signals to JavaScript that the current function should end its execution immediately, though that's most often what you want to do when you call resolve
or reject
.
