nodejs sleep method

Node.js is an event-driven asynchronous server-side JavaScript runtime environment. It is lightweight, power efficient and scalable. However, due to the asynchronous execution model of Node.js, there are some cases where wait/delay operations similar to synchronous operations need to be manually implemented. Sleep operations are often used to simulate long-running operations or in certain tasks that need to be executed after a period of time. This article will introduce how to implement sleep operations in Node.js. Method 1: Use setTimeout function set

How to implement a sleep function in nodejs

When writing JavaScript applications, you may need to add delays to your code. Single-threaded JavaScript can consume a lot of time executing synchronous functions, which can cause your application to become less responsive. In order to solve this problem, we can use an asynchronous method to achieve the "sleep" effect, which causes the program to pause execution within a specified time. This article will introduce how to use Node.js to implement a sleep function. 1. The setTimeout function in Node.js Node.js provides a built-in

The difference between sleep and wait in JAVA

The wait() method means that the current thread allows itself to temporarily surrender the synchronization resource lock so that other threads waiting for the resource can obtain the resource and run. Only when the notify() method is called, the thread that previously called wait() will be released. In the wait state, you can participate in competition for synchronization resource locks and then be executed.

Detailed explanation of sleep function function introduction and usage

In some betting websites, if we need to do a scheduled execution function, for example, there is a question that must be completed within ten seconds, otherwise it will display "You have timed out". If it is completed, jump to the next question. There is a ten-second pause in the middle. How is this function implemented? In PHP, there is a sleep function, which roughly means that when the program execution encounters the sleep function, it pauses for N seconds and then continues execution. For example, sleep(10) means that the program is executed from top to bottom. After encountering the sleep(10) statement, it pauses for ten seconds and then continues execution.
