Create a function called shortcut
to remove all the lowercase vowels in a given string.
shortcut("codewars") // --> cdwrs
shortcut("goodbye") // --> gdby
shortcut("codewars") # --> cdwrs
shortcut("goodbye") # --> gdby
shortcut("codewars") # --> cdwrs
shortcut("goodbye") # --> gdby
Shortcut("codewars") # --> cdwrs
Shortcut("goodbye") # --> gdby
shortcut "codewars" -- > cdwrs
shortcut "goodbye" -- > gdby
Don't worry about uppercase vowels.
