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. In Node.js (or programming in general), there are scenarios where we need a certain code or script executed periodically. 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.

Use a getTime synchronous method to log the exact words 'We', 'are', 'learning', and 'JavaScript' with a 2-second interval after logging the word 'We'. Try experimenting with a delayedGreeting method to separate the words: 'We', 'are', 'learning', and 'JavaScript' with a 2-second interval: If you follow this logic, the code sample looks like this: function sleep( ms), 7000) That's why you should include the async and delayedGreeting parameters to separate these three words by a 5-second interval. If you'd like to omit an asynchronous output, it could be a great way to use the async await approach. That's why this approach might not be the most suitable for putting a specific log into sleep.

Thus, the output you get will first input Learning and Script, then include Java in a 5-second timeout. When you create a delay this way, the commands work asynchronously. Output: // Learning // Script // * 5 seconds * // Java However, it's not that easy to replace one method with another and expect no downsides. This behavior will be replicated with no issues when run through a compiler. We first log the word "Java", use a setTimeout command to specify a 5-second timeout, and then attempt to log "Script". Output: // Java // * 5 seconds * // Script Let's start with a basic way to emulate sleep in JavaScript by using a setTimeout method.

Instead, you have to open a compiler on your own and see how the alternatives to sleep() behave in their natural environment. Unlike our other tutorials, this guide won't show the outputs in the console. Still, JavaScript is a flexible language, offering a few alternatives. JavaScript has no dedicated sleep() function. The sleep() function is present in PHP, C, Java, and GO, and it is used to pause the execution of code for a particular amount of time. Operators: Addition assignment operator (+=).
