setTimeout を同期的に使いたい場合、setTimeout は Promise を返さないので async / await を使って呼び出したい場合は Promise を返す関数にしてやればOK Promise を返し内部で setTimeout する関数にすればOK const sleep = (callba… Von Jan-Hendrik Eriksen ; am 30.
The two key methods to use with JavaScript are: setTimeout(function, milliseconds) Executes a function, after waiting a specified number of milliseconds. JavaScript is single-threaded therefore it can only do one task at a time. There are some approaches that can be used to simulate a sleep function. The setTimeout() method calls a function or evaluates an expression after a specified number of milliseconds. JavaScriptには処理を一時停止させる sleep 関数が存在しません。処理を一時停止させたり、待ちを発生させたい場合は setTimeout 関数を利用して実現する方法があります。
One of those features are Promises, which are probably the most widely used feature in JavaScript after ES5 was released.

Besides the JavaScript engine, the web browser has other components such as Event Loop, Call Stack, and Web API. Programmieren JavaScript: Sleep und setTimeout .
The nested setTimeout is a more flexible method than setInterval.This way the next call may be scheduled differently, depending on the results of the current one.
JavaScript features a handy couple of methods of the window object: setTimeout() and setInterval(). javascript doesn't have these kinds of sleep functions. / JavaScript Timers with setTimeout and setInterval. setTimeout は関数への参照を期待しているため、これは動作しません。 ちなみに、ここでは sayHi() 関数を実行し、その実行結果 が setTimeout に渡されます。 我々のケースでは、sayHi() の結果は undefined(関数は何も返さないため)であり、何もスケジュールされていないことになります。
Surely, callback based programming is ugly. Tip: 1000 ms = 1 second. 2~3시간을 헤맨끝에 sleep()의 문제인걸 파악했고 setTimeout() 으로 … After calling the setTimeout() function, the script continues normally, with the timer running in the background.

JavaScript does not have a native sleep function, but thanks to the introduction of promises (and async/await in ES2018) we can implement such feature in a very nice and readable way, to make your functions sleep:
It means that it can only carry a single task a given time.
