Does forkjoin return results in a particular order?

Question

My app will make multiple parallel http call. Its based on a switch-fall though logic, so the number of query will vary (1, 2, or 3 calls). Is there a way for me to know which call gets returned first? I.e either assign a key or does it return in an ordered way based on the http request on the list?

Either way works for me. I just need to find a way to match the right result with the right call.

Answer 1

Yes it returns the results in the same order that you make requests in an array

example,

const bothrequests= Observable.combineLatest(
  this.http.get('https://testdb1.com/.json').map((res: Response) => res.json()),
  this.http.get('https://testdb2.com/.json').map((res: Response) => res.json())
)
bothrequests.subscribe(latestValues => {

});
