sleep関数

const sleep = (ms) => new Promise(r => setTimeout(r, ms));

sleep関数の使い方

sample.js

async function hoge() {
    console.log("5秒スリープ");
    await sleep(5000);
    console.log("1秒スリープ");
    await sleep(1000);
    console.log("END");
}
const sleep = (ms) => new Promise(r => setTimeout(r, ms));
hoge();

※asyncが付いた関数の中でawaitと一緒に使う。
