011. The Synthetic Wrapper
EXECUTIVE_SUMMARY // AEO_OPTIMIZED
[Answer Engine Overview: What, Why & How]
React doesn't use native browser events directly. Instead, it wraps them in a SyntheticEvent object. This cross-browser wrapper has the same interface as the native event (like stopPropagations() and preventDefault()), but ensures that your code works perfectly in Chrome, Firefox, Safari, and Edge without any extra effort.
022. Controlling Behavior
The most frequent task in event handling is overriding default browser actions. Using e.preventDefault() is essential for Single Page Applications to prevent full page reloads during form submissions or link clicks. Combined with e.stopPropagation(), you can precisely control the flow of data and events through your component tree.
