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

The isObservable function from the rxjs library is used to determine whether a given object is an Observable or not. It returns a boolean value of true if the object is an Observable, and false otherwise.

To use the isObservable function, first you need to import it from the rxjs library:

index.tsx
import { isObservable } from 'rxjs';

Then, you can call the function with the object you want to check as an argument:

index.tsx
const obj = someFunctionThatReturnsAnObservable();
if (isObservable(obj)) {
  // obj is an Observable
} else {
  // obj is not an Observable
}

Alternatively, if you are not using ES6 modules, you can load the isObservable function using a script tag:

<script src="https://unpkg.com/rxjs/bundles/rxjs.umd.js"></script>

And then use it in your code:

index.tsx
const obj = someFunctionThatReturnsAnObservable();
if (rxjs.isObservable(obj)) {
  // obj is an Observable
} else {
  // obj is not an Observable
}
