简单Promise

function hiFun(){
   return new Promise((resolve,reject)=>{
       setTimeout(resole('hi'),1000);
   })
}
function call(){
  let result=hiFun()
  console.log(result)
}
call()

带async的Promise

async function hiFun(){
   return new Promise((resolve,reject)=>{
       setTimeout(resole('hi'),1000);
   })
}
function call(){
  let result=await hiFun()
  console.log(result)
}
call()

const promise1 = Promise.resolve(3);
const promise2 = new Promise((resolve, reject) => setTimeout(reject('FR01'), 100));
