__________ in AngularJS allows controllers to communicate events upwards to their parent scopes.
- $broadcast
- $emit
- $parent

$emit in AngularJS allows controllers to communicate events upwards to their parent scopes. This mechanism is part of the AngularJS Scope API, where $emit dispatches an event upwards through the scope hierarchy, making it accessible to parent scopes. Understanding this communication pattern is crucial for building complex AngularJS applications with effective component interaction.
