  > A value that is a number, true, false or null in JSON is parsed as a value.
  > E.g. '3' is a valid number while '3 times' is a string.

  > quoteless strings include everything up to the end of the
  > line, excluding trailing whitespace.

  > When you omit quotes the string ends at the newline.
  > Preceding and trailing whitespace is ignored as are escapes.
