The code above will bring no delay, and the setTimeout () will be inexistent. This delay parameter is changed to setTimeout (1000), which is a 1-second interval connected between your console.log () calls. The setTimeout () functions by delaying milliseconds. So, let’s get started! Where JavaScript Wait 5 Seconds Goes Wrong? However, the setTimeout () function can be used to make a JavaScript sleep or wait method.

Yes, many developers think of setTimeout () as sleep (), but the rules of both functions are different in their methods. Is the problem in the function of setTimeout ()?

Although sometimes, depending on the usage, it might work, but the probability is very low. The time it sets executes the code once the timer has expired. You see, the setTimeout () method (WindoworWorkerGlobalScope) is a successor to the tTimeout (). But wait, does that work? Well, in most cases, it does not. Knowing you do not have a sleep () method, you may try to come up with an alternative, something like setTimeout (). Suppose you want to log some messages and add a delay of maybe two seconds between each message. What to do if you need the JavaScript to sleep or wait? How to Wait In Javascript As we mentioned earlier, this feature is not available in JavaScript, but such a feature’s need is crucial during the development phase. It tells the code to wait for a mentioned period before being executed. The sleep function is like a timer or a signal.

Where JavaScript Wait 5 Seconds Goes Wrong?.

But after the introduction of promises in ES6, we can easily implement such a feature in JavaScript to make a function sleep: const sleep = ( ms ) => ` ) ) // Start time -> T08:35:31.993Z // After 2s -> T08:35:34.002Z // After 4s -> T08:35:36. However, this functionality is not available in JavaScript due to its asynchronous execution model.

Similarly, PHP has sleep(2), and Python has time.sleep(2) to make the program stops for 2 seconds. For example, in Java, you can use the Thread.sleep(2 * 1000) to halt the current thread execution for 2 seconds.

Many programming languages provide a sleep() function that pauses the execution of the code for a certain amount of time.
