Welcome to React JS Tutorial #19! 🎉 In this video, we dive deep into an essential concept in React: how to pass state as props between components. If you’re learning React JS and struggling to understand how state and props work together, then this video is perfect for you. 💡 We explain the difference between state and props, how to pass state from a parent component to a child, and why this concept is so powerful when building React applications.

Whether you're a beginner learning React or someone looking to brush up your concepts, this video will give you a crystal-clear understanding of how data flows in a React application. We’ll take a hands-on approach by building simple, easy-to-follow examples where we create a parent component holding state and pass it down as props to a child component. 💻

In this video, you will learn:

What is the difference between state and props in React JS

How props are used to pass data from parent to child

How state is managed within a component

How to make components reusable and dynamic using props

Best practices for working with React state and props

This concept becomes especially useful as your apps grow larger and more complex. Knowing how to pass state as props helps in building modular, reusable components, making your code more readable and maintainable. 🧠

🔥 Why is this topic important?
React’s component-based architecture relies heavily on the use of props and state. Understanding these basics is the foundation for learning more advanced topics like React Hooks, lifting state up, and context API. When you pass state as props, you allow child components to reflect and update UI based on dynamic changes in data — making your apps interactive and powerful. 🌟

👨‍🏫 Tutorial Overview:
We start by explaining the core concepts in simple terms. Then, we jump into code and show how to declare a state using the useState hook and pass that state as props to a child component. The child component receives the prop and displays the data. You'll also see how props can be used to send functions that modify state in the parent, allowing full interaction between components.
