when $digest cycle is called?

Question

I\'m very confused when a digest cycle is happening, is it called periodically based on a timer every 50ms (as it says here and implied here) or is it called after every eve

Answer 1

Any AngularJS scope variable when handled from outside (including ajax) needs a $apply().

setTimeout is Javascript function So $apply is needed to update angularjs values.

$timeout is a angularjs function which returns promise and takes care of the current scope and runs in the same digest cycle.

So need not of $apply() function to update values.
