If this parameter is omitted, a value of 0 The specified function or code is executed. The time, in milliseconds that the timer should wait before Recommended for the same reasons that make using Which is compiled and executed when the timer expires. codeĪn alternative syntax that allows you to include a string instead of a function, 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.A function to be executed after the timer expires. 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. Delaying the execution of code is a common requirement in programming.
