Key Insights

Please provide the YouTube transcript you wish me to summarize.

Concept Check

How does React handle event bubbling?

Events propagate up the DOM tree

Events only trigger at the target

Events are asynchronous only

Events are synchronous always

What's the difference between `preventDefault()` and `stopPropagation()`?

They are interchangeable

Both prevent default actions

Both stop event propagation

One stops default, other bubbling

In React, how do you pass arguments to an event handler?

Using arrow functions or bind()

Directly passing in the event

Using anonymous functions only

Arguments are ignored by React

Why might you use `event.currentTarget` instead of `event.target`?

For better performance

To target a specific child element

To access the event handler's element

They are functionally identical

Explain the use of callback refs in event handling.

Direct DOM element access

They are deprecated in React

To manage component state

For improved event speed
