Return multiple variables on async/await

rated 0 times [ 4] [ 3] / answers: 1 / hits: 19383 / 7 Years ago, thu, september 7, 2017, 12:00:00

I was wondering if there is a way to get the second resolve value (test2) without returning arrays or JavaScript objects.

function testFunction() {

  return new Promise(function(resolve, reject) {

    resolve(test1, test2);

  });

}



async function run() {

  var response = await testFunction();

  console.log(response); // test1

}



run();

You can pass only one item. But starting from ES6 there is a good feature called Array Destructuring.

Return an array and you can leave the properties assignment under the hood.

function testFunction() {

    return new Promise(function(resolve, reject) {

  	       resolve([ test1, test2] );

           });

}



async function run() {



  const [firstRes, secondRes] = await testFunction();

  

  console.log(firstRes, secondRes);



}



run();
