How React Works

Before diving straight into our first React application, let's take a look at one of React's specificities: its syntax.

When you look at a React file (here a HelloWorld component), you might think you're writing HTML:

function HelloWorld() {
  return (
    <h1>Hello React</h1>
  )
}

But this is not HTML, it's JSX, a syntax specific to React.

JSX stands for JavaScript XML. It's an extension that allows you to write tags directly within JavaScript code, somewhat like templates.
