how to use the noop function from the rxjs library in javascript

The noop function from the rxjs library is a utility function that returns a function that does nothing. It can be useful as a placeholder when you need to pass a function as an argument but don't actually want it to do anything.

Here's an example of how to use the noop function in JavaScript:

index.tsx
import { noop } from 'rxjs';

function doSomething(callback) {
  callback();
}

doSomething(noop); // This will execute without doing anything
143 chars
8 lines

In the example above, we import the noop function from the rxjs library and pass it as a callback to the doSomething function. Because noop returns a function that does nothing, the callback function that is passed to doSomething will execute without actually doing anything.

Alternatively, you can define a no-operation function yourself:

index.tsx
function noop() {}
19 chars
2 lines

This function will also do nothing and can be used in place of the rxjs noop function.
