Instructor:

"Hi there, and welcome back! So far, we’ve learned how to pass data between components using props. But what if a component needs to manage its own changing data? That’s where state comes in!

By the end of this lesson, you’ll understand:

• What state is and why it’s essential in React.
• How to manage state in functional components using the useState hook.
• How to update and read state values dynamically.

Let’s get started and see state in action!"

1. Understanding State and Its Role in React

Instructor:

"State is a built-in React feature that allows components to store and manage data that can change over time.

Unlike props, which are passed from a parent component, state is managed inside a component. When state changes, React automatically re-renders the component to reflect the new data.

Real-Life Analogy:

"Think of state like a digital scoreboard at a basketball game.

• The score starts at zero.
• Every time a team scores, the numbers update automatically.
