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

To use the throttle function of RxJS library in JavaScript, you need to first install RxJS using the npm package manager through the command line:

npm install rxjs

After installing, you can import it in your code like this:

index.tsx
import { fromEvent } from "rxjs";
import { throttleTime } from "rxjs/operators";

const button = document.querySelector('button');
const clicks = fromEvent(button, 'click');
const result = document.querySelector('#result');

clicks.pipe(
    throttleTime(1000)
).subscribe(() => {
    result.innerHTML = "<p>Button clicked!</p>";
});

In the above example, we are creating a click event observable using fromEvent method, and then using the throttleTime operator to throttle the click events by a specified duration of 1000 ms (1 second).

This ensures that only one button click event will be emitted within the specified duration, and any additional clicks that occur during that duration will be ignored.

Finally, we subscribe to the throttled clicks observable and update the result element accordingly.

Hopefully, this helps you in understanding how to use the throttle function from the RxJS library in JavaScript programming.
