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

The repeat operator from the rxjs library in JavaScript is used to repeat an observable sequence a specific number of times. Here's an example of how to use the repeat operator:

index.tsx
const { of } = require('rxjs');
const { repeat } = require('rxjs/operators');

const source = of(1, 2, 3);

source.pipe(
  repeat(3)
).subscribe(console.log);

In this example, we create an observable sequence using the of operator and pass in the values 1, 2, and 3. We then pipe this observable sequence through the repeat operator and specify that we want it to repeat 3 times. Finally, we subscribe to the repeated sequence and log the values to the console.

Note that repeating an observable sequence without specifying a number of repetitions will result in an infinite loop, so be sure to include a number of repetitions or use the take operator to limit the number of emissions.
