E0115: unexpected 'case' outside switch statement

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

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

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

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