Promiseのテスト

あえてアロー表記で書いてみる

'use strict';

let promise = () => {
  return new Promise((resolve, reject)=>{
    setTimeout(()=>{resolve('Async hello world')},16)});
}

let callbackFunc = (value) => {
  console.log(value);
}

let handleFunc = (error) => {
  console.log(error);
}

promise()
.then(callbackFunc)
.catch(handleFunc);
