//Array syntax
let promises = [promiseOne(), promiseTwo(), promiseThree()];

$q.all(promises).then((values) => {
    console.log(values[0]); // value One
    console.log(values[1]); // value Two
    console.log(values[2]); // value Three
  
//   do something

//object syntax
let promises = {
    one: promiseOne(),
    two: promiseTwo(),
    three: promiseThree()
}
$q.all(promises).then((values) => {
    console.log(values.one); // value one
    console.log(values.two); // value two
    console.log(values.three); // value three

let p1 = new Promise((resolve, reject) => {
  setTimeout(resolve, 100, "foo");
});

let p2 = new Promise((resolve, reject) => {
  setTimeout(resolve, 200, "bar");
});

let p3 = new Promise((resolve, reject) => {
  setTimeout(resolve, 300, "baz");
});

Promise.all([p1, p2, p3]).then(values => { 
  console.log(values); // ["foo", "bar", "baz"]
