Execution order of multiple setTimeout without delays in angular

673 views Asked by At

What is the execution order of multiple setTimeout without delays in angular2+?

Example:

setTimeout(() => console.log('1'));
setTimeout(() => console.log('2'));

Questions:

(1) Is 1 always guaranteed to be printed before 2?
(2) If so, what part of the spec says so?
(3) This is called in Angular2+ code. Is angular overriding setTimeout's default behaviour?

How it differs from other questions:

This question (1) asks about the case without delay, and (2) asks it in angular context (in case angular overrides setTimeout).

Non-questions:

I know console.log might (or might not) be async or whatever; this question is not related to that. You can assume console.log is sync.

1) Yes

2) Step 16 of https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html which says:

Wait until any invocations of this algorithm that had the same method context, that started before this one, and whose timeout is equal to or less than this one's, have completed.

3) No, Angular does not override it.
