How do you properly return multiple values from a promise?

Question

I\'ve recently run into a certain situation a couple of times, which I didn\'t know how to solve properly. Assume the following code:

somethingAsync()
  .the         


        

Answer 1

Simply make an object and extract arguments from that object.

let checkIfNumbersAddToTen = function (a, b) {
return new Promise(function (resolve, reject) {
 let c = parseInt(a)+parseInt(b);
 let promiseResolution = {
     c:c,
     d : c+c,
     x : 'RandomString'
 };
 if(c===10){
     resolve(promiseResolution);
 }else {
     reject('Not 10');
 }
});
};

Pull arguments from promiseResolution.

checkIfNumbersAddToTen(5,5).then(function (arguments) {
console.log('c:'+arguments.c);
console.log('d:'+arguments.d);
console.log('x:'+arguments.x);
},function (failure) {
console.log(failure);
});
