export 'default' (reexported as code example

Example 1: export default react

import React from 'react'; // get the React object from the react module

class HelloWorld extends React.Component {
  render() {
    return <p>Hello, world!</p>;
  }
}

export default HelloWorld; // expose the HelloWorld component to other modules

Example 2: javascript export default

export default const array = [1, 2, 3];
export default let array = [1, 2, 3];
export default var array = [1, 2, 3];
export default const variable = 'value';
export default let variable = 'value';
export default var variable = 'value';
export default const variable;
export default let variable;
export default var variable;
export default function functionName () {
  // ...
}
export default class ClassName {
  // ...
}
// Before you use export default: You can't have 2 or more export default's.
