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

Here is an example of how to use the isObservable function from the rxjs library in TypeScript:

index.ts
import { isObservable, Observable } from 'rxjs';

function myFunction(input: any): void {
  if (isObservable(input)) {
    // Input is an Observable
    const myObservable: Observable<any> = input;
    myObservable.subscribe(value => console.log(value));
  } else {
    // Input is not an Observable
    console.log('Input is not an Observable');
  }
}

In this example, we import the isObservable function and the Observable class from the rxjs library. We then define a function called myFunction that takes an input parameter of type any.

Inside the function, we use the isObservable function to determine if the input parameter is an instance of the Observable class. If it is, we cast the input parameter to an Observable object and subscribe to it, logging each value emitted by the Observable. If it is not an Observable, we simply log a message to the console indicating that input is not an Observable.
