What is AngularJS performance profiling strategy in enterprise systems?

Performance profiling involves analyzing digest cycles, watcher counts, and DOM rendering bottlenecks.

Enterprise AngularJS apps require profiling using Chrome DevTools, Batarang (legacy), and custom instrumentation. Key metrics include digest cycle duration, watcher count, and memory usage. Bottlenecks often come from deep watches, large ng-repeat lists, and excessive bindings.
