## E0107: expected '{'

A `switch` statement has a list of cases. It is a syntax error to omit `{` after the condition of a `switch` statement:

    function colorToHexCode(color) {
      switch (color)
        case 'red':   return '#ff0000';
        case 'green': return '#00ff00';
        case 'blue':  return '#0000ff';
      }
    }

To fix this error insert a `{` after the condition:

    function colorToHexCode(color) {
      switch (color) {
        case 'red':   return '#ff0000';
        case 'green': return '#00ff00';
        case 'blue':  return '#0000ff';
      }
    }
