export default react
import React from 'react'; // get the React object from the react module
class HelloWorld extends React.Component {
render() {
return Hello, world!
;
}
}
export default HelloWorld; // expose the HelloWorld component to other modules
Here is what the above code is Doing:
1. We’re importing the React object from the react module.
2. We’re creating a new class called HelloWorld that extends the React.Component class.
3. We’re defining a render method that returns a
Hello, world!
element.
4. We’re exporting the HelloWorld class, so other modules can use it.
