JSX

JSX

JSX 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 jsx 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 jsx 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 jsx

// React: JSX
function demo() {
  console.log("Exploring JSX 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 jsx.
