Summary  
This chapter explains how to handle user events by passing handler functions (e.g., via onClick and onChange) to React elements and using the event object (such as event.target.value) to respond to user actions dynamically.

General domain of usage  
Interactive web interfaces

User interfaces become interactive when they respond to user actions such as clicks and input changes.

In React, events are handled by passing functions to elements using special attributes like `onClick` and `onChange`.

For example, a button click can trigger a function:
```jsx
function App() {
  function handleClick() {
    console.log("Button clicked");
  }

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

When the button is clicked, the function is executed.

You can also handle input changes:
```jsx
function App() {
  function handleChange(event) {
    console.log(event.target.value);
  }

  return <input onChange={handleChange} />;
}
```

The `event` object contains information about the user action. For inputs, the current value is available as `event.target.value`.

Event handling allows your components to respond to user behavior and update the interface dynamically.

Explore how React is used to build dynamic user interfaces using components, JSX, and props. Manage state and side effects with hooks, render lists and conditional UI, and apply styling to real components. Set up a React project with Vite and understand how applications are structured.
