Isn't the sleep() function in Linux thread-safe? The "sleep()" function in the Linux environment is thread-safe, that is, multiple threads can safely call the "sleep()" function concurrently without problems. The "sleep()" function is mainly used to pause the execution of the current thread for a period of time. Time, give up the CPU to other threads or processes. When the "sleep()" function is called, it will cause the current thread to enter the blocking state until the specified time interval passes, and then the thread will become runnable again.

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
