js 異步for循環

假設一名廚師，須要作3道菜,聲明一個菜數組，菜對象是菜名和作菜須要的時間

let dishes=[{name:"fish",time:1},{name:"fish1",time:2},{name:"fish3",time:3}]

首先，廚師作菜應該一道接一道的作，因此得保證一道菜作後纔開始作下一道菜。這裏用async/await實現，固然也能夠選擇都用Promise

(async ()=>{
      for (let d of ds) {
          console.log("開始作"+d.name)
          await (() => {
            return new Promise(res => {
              setTimeout(res, d.time * 1000)
            })
          })();
          console.log("作好了"+d.name)
        }
    })
