Promises - serial

gistfile1.js

const asyncA = () => Promise.resolve('A');
const asyncC = (prefix) => Promise.resolve(`${prefix}+C`); // e.g. "x+C"

// Please write a function that calls these 2 async functions and combines the results into a single object.
// asyncC takes the "prefix" argument - should be the resolved result of the asyncA() promise (which means asyncC depends on asyncA).
// Basically, first need to call asyncA, then pass the result to asyncC, then combine the both results into the single output object.
const callAsync = () => {
  // your code should be here
  // ...
}

callAsync().then(result => console.log(result)); // should print: {a: 'A', c: 'A+C'}
