Question - What does Asynchronous means in the context of RxJS or Reactive programming?
Answer -
According to the Oxford Dictionary, the term asynchronous can be defined as "not existing or occurring at the same time." In the context of Reactive programming, it means that the processing of a request occurs at an arbitrary point in time, sometime after it has been transmitted from client to service. The client cannot directly observe, or synchronize with, the execution that occurs within the service. Asynchronous is the antonym of synchronous processing, which implies that the client only resumes its execution once the service has processed the request.
