WhiteSpace is the collection of characters (in ASCII or Unicode) that leave blank space but no ink on the page. They include spaces, tabs, new lines, etc.

Whitespace is a ProgrammingLanguage similar to Brainf*ck, which uses only spaces, tabs and newlines as syntax. This means any letters/etc are ignored, so you can just type in comments inline (without whitespace chars, of course).
