![]() This is an effective way of achieving delayed execution, as opposed to using only the `setTimeout` function which does not stop the execution of subsequent lines. The example provided shows how to use the `async/await` pattern along with a custom `sleep` function that returns a Promise in order to delay the execution of code. ![]() The execution of the next line after `await sleep(1000) ` will be delayed for 1 second. The `delayedExecution` function is an `async` function, which allows you to use the `await` keyword to wait for the Promise to resolve. In this example, the `sleep` function takes a number of milliseconds as an argument and returns a Promise that resolves after the given time. Return new Promise(resolve => setTimeout(resolve, ms)) Īwait sleep(1000) // Wait for 1000 milliseconds (1 second) Here’s how you can create a `sleep` function using Promises and use it to delay the execution of the code: To achieve the required functionality, you can use the `async/await` pattern along with a custom `sleep` function that returns a Promise. However, since JavaScript is asynchronous by nature, using `setTimeout` won’t stop the execution of the code that comes after it. In JavaScript, you can use `setTimeout` function to delay the execution of a specific block of code. This blog post will explain how to create such a sleep function and demonstrate its usage for delaying code execution. To achieve this functionality, we can use an `async/await` pattern along with a custom `sleep` function that returns a Promise. In JavaScript, you can use `setTimeout` to delay the execution of a specific block of code. The JavaScript setTimeout () method is a built-in method that allows you to time the execution of a certain function. That is why your first alerts pops up after 3 seconds, and all the rest follow in succession without any delay. Therefore your loop will iterate very quickly and it will initiate 3-second timeout triggers one after the other in quick succession. Delaying the execution of code is a common requirement in programming. 1 2 Next 945 +50 The setTimeout () function is non-blocking and will return immediately.
