how to use rxjs zip in javascript

To use zip operator in RxJS, you need to import it from the rxjs package. The zip operator combines the values from multiple observables into an array. Here's an example of how to use zip in JavaScript:

index.tsx
// Import the required operators and functions
import { zip } from 'rxjs';
import { map } from 'rxjs/operators';

// Create two observables
const observable1 = of('Hello');
const observable2 = of('World');

// Use the zip operator to combine the values
const zippedObservable = zip(observable1, observable2);

// Subscribe to the zipped observable
zippedObservable.pipe(
  map(([value1, value2]) => `${value1} ${value2}`)
).subscribe(result => {
  console.log(result);
});

// Output: "Hello World"

In this example, the zip operator takes two observables (observable1 and observable2) and combines their values into an array. The map operator is used to transform the array into a string by concatenating the values. Finally, the result is logged to the console.

Make sure to install the rxjs package by running npm install rxjs before using it in your JavaScript project.
