SETTIMEOUT NODEJS CODE

Under the async function, we have used the keyword await() to suspend the second console.log() function until the promise has been resolved this takes an average of 4 seconds. We will name this function sleep() however, that does not stop you from naming it to any other name that you may find appropriate.

However, using an asynchronous promise-based function, we can use the keyword await() to pause the execution of a piece of code until that promise is fulfilled first. Unlike other programming languages such as C that provide a sleep function, which allows us to sleep a given thread while waiting for another to execute, JavaScript doesn’t have this function. The following code shows a quick example of setTimeout, which calls a. Use the await() Keyword to Pause Execution of Codes in Node.js setTimeout sets up a function to be called after a specified delay in milliseconds. Sample output: Function repeatedly executed after every 2 seconds!įunction repeatedly executed after every 2 seconds! Here is a simple example of using the setTimeout() function to execute functions at a different time interval specified as milliseconds. Since the Timer object is a global object, we need not require() anything in our code when working with the setTimeOut() function.

This module provides various methods that we can use to schedule functions to be called after some specified time. This is a Node.js module available through the npm registry. This function returns an integer known as the timeout ID that can reference the object created by the setTimeout() function. The setTimeOut() function is provided under the Timers module. Times out a request in the Connect/Express application framework. Some code that will run after the set time is over any other arguments specified in the function to be executed.The number in milliseconds that the timer will wait before executing the specified function.The function to be executed after the set time interval.The setTimeout() function accepts many parameters, two of which are compulsory while the rest are optional. The setTimeout() method is an asynchronous method that allows us to execute a function once after given time intervals. setInterval() Use the setTimeout() Method to Schedule the Execution of Codes in Node.js.Node.js provides us with two built-in functions that we can use to schedule the execution of functions in Node.js and JavaScript. This method is used to schedule the execution of code after a given period in milliseconds. In this section, we will look at the Node.js setTimeout() method. As discussed earlier, Node.js API provides utilities, which enable us to execute code at a later time based on our requirements. In Node.js (or programming in general), there are scenarios where we need a certain code or script executed periodically. Scheduling timers using setTimeout() method. Use the await() Keyword to Pause Execution of Codes in Node.js.Use the setInterval() Method to Schedule the Execution of Codes in Node.js.Use the setTimeout() Method to Schedule the Execution of Codes in Node.js.
