Delay Async Function Execution in JavaScript

Introduction

In this lab, we will explore how to delay the execution of an asynchronous function in JavaScript. By using the sleep function and returning a Promise, we can put a part of the async function to sleep for a certain amount of time, allowing for better control and management of the code's execution. Through practical examples, we will learn how to effectively implement this technique in real-world scenarios.

How to Delay Execution of an Async Function in JavaScript

To delay the execution of an asynchronous function in JavaScript, you can use the sleep function below, which returns a Promise that resolves after a certain amount of time. Here's an example of how to delay the execution of part of an async function using sleep:

const sleep = (ms) => new Promise((resolve) => setTimeout(resolve, ms)); async function sleepyWork() { console.log("I'm going to sleep for 1 second."); await sleep(1000); console.log("I woke up after 1 second."); }

To use this function, simply call sleepyWork() and the console will log the messages with a 1 second delay between them.
