9000ms 정도 걸린다
async function timeTest() {
await timeoutPromise(3000);
await timeoutPromise(3000);
await timeoutPromise(3000);
}3000ms 정도 걸린다
async function timeTest() {
const timeoutPromise1 = timeoutPromise(3000);
const timeoutPromise2 = timeoutPromise(3000);
const timeoutPromise3 = timeoutPromise(3000);
await timeoutPromise1;
await timeoutPromise2;
await timeoutPromise3;
}그간 기계적으로 const response = await timeoutPromise(); 처럼 Promise 결과값 할당과 동시에 await 붙였었는데 조심해야겠다.
