making the same $http request simultaneously

Question

What happens if I make the same $http request - same params, etc- simultaneously in the app? Does one wait for the others' response?

And if I make them back to back. If the first one is not resolved yet, do the others wait for that?

You mean like having two threads running the same call? That's literally impossible because JavaScript is single-threaded — Maria Ines Parnisari, Jul 11 '16 at 14:24
yea. if you make them back to back by calling second `$http` request inside first one, then of course, second one will wait for first one. — Varit J Patel, Jul 11 '16 at 14:27

There is a limit for browsers request count See Max parallel http connections in a browser?

Think each request independent , angularjs $http service return a promise object and you register its success and error callbacks.

Read more about from here https://docs.angularjs.org/api/ng/service/$http

See my plunk below. If I call multiple calls I see them parallel in network tab. But this doesn't cause a conflict because we have different promises and their callbacks will be different. call 1 promise instance1 ... call N promise instance N
