When making visual effects like animations, pausing the code is also essential because it lets the program wait for a certain amount of time before going on.Īnother reason to pause your code is to avoid overloading a remote API with too many requests. Additionally, it can pause the action at strategic points in the program. For example, it can be used to stop code execution to wait for certain tasks, like a network request, to finish. Pausing code in Node.js is an important concept, as it is used in various situations. We’ll look at the pros and cons of each method as well as how to use sleep in Node.js most effectively.
This article will look at setTimeout and setInterval, two ways to make your Node.js code pause.
The sleep function can be useful when you want to wait for an asynchronous task to finish or when you need to add a delay so that you don’t send too many requests to a remote API. However, in some cases, you should pause the execution of Node.js code. Node.js is a great choice for real-time web apps with many connections because it can handle multiple connections simultaneously with a single-threaded event loop. Node.js has a JavaScript runtime environment, and developers can make scalable, high-performance server-side apps.
