Instructor:

"Hi there, and welcome back! In the last video, we explored JSX and its powerful features. Now, let’s talk about one of the core concepts of React: components.

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

• What components are and why they’re crucial in React.
• The two main types of components: functional and class components.
• How to pass data to components using props to make them dynamic.

Components are at the heart of React, so mastering them is essential. Let’s dive in!"

1. What Are Components, and Why Are They Important?

Instructor:

"Components are the building blocks of a React application. They are like self-contained, reusable pieces of code that define how a part of your UI should look and behave.

For example, think about a social media app:

• A post is a component.
• A like button is a component.
• A profile card is a component.

Each of these components can be developed independently and reused throughout the app. This modular approach makes React apps scalable, maintainable, and efficient."

Real-Life Analogy:

"Imagine building a car. Instead of assembling it from scratch, you use prebuilt parts like the engine, tires, and seats. Similarly, in React, you build an app by combining reusable components."
