Angular2: setTimeout only called once

javascript angular typescript settimeout

 private authenticate_loop() {    setInterval (() => {      console.log("Hello from setInterval");    }, 500) }

setTimeout will run just one time, unless you create another setTimeout.

javascript angular typescript settimeout

Edit: So to be more specific for the different angular versions:

In Angular2 you are not required to use $timeout / $interval any more. So for the question here setInterval is the correct solution.

For any one interested in the original response (targeted to Angular1) read the following:

Use $interval inside an angular.js application.

And if you want to use setTimeout somewhere else inside an angular.js application you should better use the $timeout service.

$timeout and $interval have the advantage, that they keep your scope updated, which setTimeout / setInterval do not.
