setImmediate() nodejs

setImmediate() is a function in Node.js that allows you to schedule a callback function to be executed immediately after the current phase of the event loop.

Here are the steps involved in using setImmediate() in Node.js:

  1. First, you need to require the setImmediate() function from the timers module in Node.js. You can do this by using the require() function and passing in the name of the module as a parameter:

javascript const { setImmediate } = require('timers');

  1. Once you have required the setImmediate() function, you can use it to schedule a callback function to be executed immediately after the current phase of the event loop. To do this, you need to pass the callback function as a parameter to the setImmediate() function:

javascript setImmediate(() => { // Your callback function logic here });

The callback function will be executed asynchronously, meaning that it will not block the execution of the rest of your code.

  1. You can also pass additional arguments to the callback function by specifying them after the callback function:

javascript setImmediate((arg1, arg2) => { // Your callback function logic here }, arg1, arg2);

The additional arguments will be passed to the callback function when it is executed.

  1. You can cancel the scheduled immediate callback using the clearImmediate() function. This function takes a single parameter, which is the immediate object returned by the setImmediate() function:

```javascript const immediateObject = setImmediate(() => { // Your callback function logic here });

clearImmediate(immediateObject); ```

Calling clearImmediate() will prevent the callback function from being executed.

That's it! These are the steps involved in using setImmediate() in Node.js. It allows you to schedule a callback function to be executed immediately after the current phase of the event loop.
