The only code snippet that works is the first one. All others throw some kind of error or have side effects.
forEach throws Uncaught SyntaxError: Unexpected token [ because of the weird function declaration.
Uncaught SyntaxError: Unexpected token [
map throws Uncaught SyntaxError: Unexpected token new. Why would anyone name a variable new?
Uncaught SyntaxError: Unexpected token new
new
Set does work, but modifies the original array. Nick Taylors solution [...new Set(array)] does the same but better.
[...new Set(array)]
