Components

Components

Components is a core part of React. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding components well means you can read other people's React code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What components means in the context of React
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with components

// React: Components
function demo() {
  console.log("Exploring Components in React");
}

demo();

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for components.
