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. Syntax of JavaScript Sleep Function: sleep(delayTime in milliseconds).Node.js has a JavaScript runtime environment, and developers can make scalable, high-performance server-side apps. Here, we can observe the asynchronous behavior of JavaScript as it does not waits for anything while execution and continues its work further. Refer to the URL to get the data referred for displaying. then(sampleJson => console.log(ssage)) console.log('Hello!') Īs we can see in ruby, firstly the data from the URL is fetched, and then the message property value “Not Found” is displayed and after that the static message saying “Hey! Let us have a look at message.” is displayed while in case of JavaScript, firstly the request for getting the URL data is sent and JavaScript does not wait till the response comes, instead it executes the second statement displaying “Hello” on console and when the response of the sent request arrives, it displays the message value saying “Not Found”. then(sampleResponse => sampleResponse.json()) Where “Not Found” is the message string stored in the issues section on the mentioned github url. Puts 'Hey!Let us have a look on message.' SampleResponse = JSON.parse(Net::HTTP.get(sampleUri)) puts sampleResponse SampleUrl = '' sampleUri = URI(sampleUrl)
