I have question if i change any instance varible values it will trigger ng do check then ng after content init and so on if try to modify the instance varible in ng docheck then it will be in loop mode?

[@WebTechTalk]

ngDoCheck is called whenever change detection runs. Is your instance variable cause a change detection. For example, if you change that on a button click it will invoke change detection. If you just change the value, it will reflect in the DOM only. But if refreshing the DOM triggers ngDoCheck by any other means, it will become a loop.
