There are some good answers here already. But it’s worthwhile to drive home the difference in parallelism offered:
success()
returns the original promisethen()
returns a new promise
The difference is then()
drives sequential operations, since each call returns a new promise.
$http.get(/*...*/).
then(function seqFunc1(response){/*...*/}).
then(function seqFunc2(response){/*...*/})
$http.get()
seqFunc1()
seqFunc2()
success()
drives parallel operations, since handlers are chained on the same promise.
$http(/*...*/).
success(function parFunc1(data){/*...*/}).
success(function parFunc2(data){/*...*/})
$http.get()
parFunc1()
,parFunc2()
in parallel
