React handles events using a synthetic event system, which is a cross-browser wrapper around the native browser events. This system ensures that events behave consistently across different browsers and improves performance by using event delegation.

🔹 Key Concepts of Event Handling in React:

1. SyntheticEvent

• React wraps browser events in a SyntheticEvent object.

• This provides a consistent API for all browsers.

• It pools events for performance, meaning the event object is reused (so avoid async access without calling event.persist()).

2. CamelCase and JSX

• Event names use camelCase instead of lowercase (e.g., onClick instead of onclick).

• Event handlers are passed as functions, not strings (unlike HTML).
