how to use rxjs zipall in javascript

To use the zipAll operator in RxJS, you first need to install the RxJS library and import zipAll from it. Here's an example of how to use zipAll in JavaScript:

index.tsx
// Import the necessary functions from RxJS
import { of } from 'rxjs';
import { zipAll } from 'rxjs/operators';

// Create observables
const source1 = of(1, 2, 3);
const source2 = of('A', 'B', 'C');
const source3 = of(true, false, true);

// Zip the values emitted by all observables
source1.pipe(
  zipAll()
).subscribe(result => console.log(result));

/* Output:
   [1, 'A', true]
   [2, 'B', false]
   [3, 'C', true]
*/

In this example, zipAll is used to combine the values emitted by source1, source2, and source3 into a single array. Each emitted value from each source observable is combined based on their index.

Make sure to install the RxJS library before running this code. You can install it using npm or yarn:

npm install rxjs

Please note that zipAll is an operator that works on observables, so it requires the use of a scheduler. The zipAll operator also waits for all observables to complete before emitting values.
