Delay Function Execution in JavaScript

Introduction

In this lab, we will be exploring the delay() function which allows us to delay the execution of a given function by a specified number of milliseconds. This function is useful in scenarios where we need to add a pause in our code execution, for example, when working with animations or performing time-sensitive tasks. Through this lab, we will learn how to use the delay() function effectively in our JavaScript code.

How to Delay Function Execution in JavaScript

To delay the execution of a function in JavaScript, you can use the setTimeout() method. Here's how to do it:

Open the Terminal/SSH and type node to start practicing coding.

Use the following syntax to delay the execution of a function fn by ms milliseconds:

const delay = (fn, ms, ...args) => setTimeout(fn, ms, ...args);

To pass arguments to the function, use the spread (...) operator like this:

delay( function (text) { console.log(text); }, 1000, "later" ); // Logs 'later' after one second.

With this code, the provided function fn will be invoked after the specified number of milliseconds (ms). The ...args parameter allows you to pass an arbitrary number of arguments to the function.
