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

To use the sample function from the RxJS library in JavaScript, you first need to install the library by running npm install rxjs in your terminal.

Then, you can import the sample function along with other RxJS functions as follows:

index.tsx
import { fromEvent, interval } from 'rxjs';
import { sample } from 'rxjs/operators';
85 chars
3 lines

In this example, we are also importing the fromEvent and interval functions from RxJS, which will be used to create an observable that emits mouse clicks and another observable that emits a value every second.

index.tsx
const clicks = fromEvent(document, 'click');
const timer = interval(1000);
75 chars
3 lines

Next, you can use the sample function to sample the emitted values of the clicks observable every time the timer observable emits a value:

index.tsx
const sampledClicks = clicks.pipe(sample(timer));
50 chars
2 lines

Finally, you can subscribe to the sampledClicks observable to log the sampled clicks to the console:

index.tsx
sampledClicks.subscribe(val => console.log(val));
50 chars
2 lines

This will output the coordinates of the last clicked position every second.
