When to favor ng-if vs. ng-show/ng-hide?

Question

Answer 1

ng-if on ng-include and on ng-controller will have a big impact matter on ng-include it will not load the required partial and does not process unless flag is true on ng-controller it will not load the controller unless flag is true but the problem is when a flag gets false in ng-if it will remove from DOM when flag gets true back it will reload the DOM in this case ng-show is better, for one time show ng-if is better
