Typed Event Handling & Custom Events

Implement type-safe event handling for native DOM events and custom events in Vue 3 and React 18. Vue uses defineEmits with TypeScript type annotations for custom events, while React leverages typed event handlers with React's SyntheticEvent types. This pattern ensures type safety for event payloads and prevents invalid event usage. Use cases: Form submissions, custom component interactions, keyboard/mouse events with typed payloads.
