// Orange indicators means only part of the line was executed
// because JavaScript stops processing after first false value

// on a line of code

  // White indicators means that a line of code was never
  // executed by Quokka

// Red indicators show where an error occurred. The error message
// is also shown beside the error
// throw new Error('Something went wrong');
