How to stop digest cycle manually in angularjs

Question

As digest cycle do the dirty checking of the variable that is if there are 100 scope variables and if I change one variable then it will run watch of all the variables.

Answer 1

This is quite a specific use-case to do exclusive/conditional checks in the digest cycle and I don't think it is possible without forking/hacking the angular core.

I would consider refactoring how/what you are $watching. Perhaps using ngModelController's $viewChangeListeners would be more suitable than $watch?
