Replace With Alphabet Position

/*
// Given a string, replace every letter with its position in the 
alphabet.
// If anything in the text isn't a letter, ignore it and don't return it.
"a" = 1, "b" = 2, etc.

  Example
  alphabetPosition("The sunset sets at twelve o' clock.")
  Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" ( as a string )
*/

const alphabetPosition = text => text.replace(/[d|W|_]/g, "").split("")
			.map(letter => letter.charCodeAt(0) & 31).join(' ');
