Angular timeout ($timeout) service promise

In angular JS, if you want perform some action after some time (or you want to wait for some time) you can use $timeout service. This service returns the promise which we can resolve by "then". In following example, it will take 2 seconds to call the function "toBeCalled".


function Controller($timeout) {

           wait(2).then(function () {

            })

            function wait(seconds) {
                return $timeout(toBeCalled, seconds * 1000);
            }

            function toBeCalled() {
                console.log("called after 2 seconds");
            }
        }
