What is the syntax of angular's settimeout()?

Angular's setTimeout() is a powerful method that acts like a JavaScript timer. It is used to wait for a certain amount of time before executing a specific task. With the help of setTimeout() you can easily handle delays in an Angular application. This article will discuss the syntax of Angular's setTimeout() and its purpose.

The syntax of Angular's setTimeout() is quite simple and can be written in one line. It is written as follows:

setTimeout(callback, delay);

Here, the callback parameter represents a function that needs to be executed after the specified delay value (which is specified in milliseconds). Let's consider an example to better understand how it works.

Let's say we have a application which prints 'Hello world' after 5 seconds delay. In this case, we would use setTimeout() as follows:

setTimeout(function () { console.log("Hello World!); }, 5000);

In the above code, we provided 2 parameters to the setTimeout() method — a function that prints 'Hello world' and 5000 (5 seconds) as delay value (in milliseconds). In other words, this code will wait for 5 seconds before printing 'Hello world' on the console.

Now let's say you want to stop that specific task from running after 12 seconds instead of 5 seconds and you updated your code snippet like this:

setTimeout(function () { console.log("Hello World!); }, 12000); // 12000 corresponds to 12 second delay value

This code will print 'Hello World!' on your console after 12 seconds instead of 5 seconds since we have updated our delay value with 12000 (12 seconds).
