What are synthetic events in React?

What are synthetic events in React?

Synthetic events are a cross-browser wrapper around the browser's native events. They normalize events so that they have consistent properties across different browsers.

How do synthetic events differ from native events?

Synthetic events are pooled for performance reasons, meaning they are reused across multiple events. This can lead to some differences in behavior, such as the event properties being nullified after the event callback.

Can you give an example of how to use synthetic events in a React component?

Sure! In a React component, you can handle a synthetic event like this:

function MyComponent() {
  const handleClick = (event) => {
    console.log(event); // This is a synthetic event
  };

  return <button onClick={handleClick}>Click me</button>;
}
