What is the difference between observer and subscriber in RXJS?

See the code below

// subscriber being used
const observable = new Observable(subscriber => {
  subscriber.next(1);
  subscriber.next(2);
})

// observer being used
const observable = new Observable(observer => {
  observer.next(1);
  observer.next(2);
})

What is the difference between observer and subscriber in the context above?

Solution

  • These are the same. In this case, subscriber or observer is just the name given to the function parameter. You could call it anythingYouWant and it would function the same:

    const observable = new Observable(anythingYouWant => {
  anythingYouWant.next(1);
  anythingYouWant.next(2);
})
