## E0116: unexpected 'default' outside switch statement

`switch` statements can contain a `default` label. It is a syntax error to write a `default` label outside a `switch` statement:

    function colorToHexCode(color) {
      switch (color) {
        case 'red':   return '#ff0000';
        case 'green': return '#00ff00';
        case 'blue':  return '#0000ff';
      }
        default:
          throw new Error(`unknown color ${color}`);
    }

To fix this error, move the `default` label into a `switch` statement:

    function colorToHexCode(color) {
      switch (color) {
        case 'red':   return '#ff0000';
        case 'green': return '#00ff00';
        case 'blue':  return '#0000ff';
        default:
          throw new Error(`unknown color ${color}`);
      }
    }
