.then(x => result1 = x);
I am working with promises on nodejs and i want to pass a parameter to a promise function. I'm trying to learn what promise is, so i started following this guide. .then(x => result2 = x);. Wrapping a promise in an asynchronous function is still asynchronous.
Whether it's an es6 promise or a bluebird promise, q promise, etc. How can the result of a resolved promise be obtained immediately?
