hey, guys. im new to ng2 . I have a question about variable observation.
When I use ng 1, i use $watch to check if the specific part of a variable
is changed.
*$scope.$watch('options[uuid].properties.style', function () {
doSomething()}, true);*
the object *options *could be changed somewhere else.
when the part in *options *changed, it will trigger a function and do
something.
i wanna know how can i do this if i use ng 2.
there must be some way, right?
