Sometimes you just need to take strings apart:
var sentence = "Oh a cookie!"
sentence.split(" ");
// [ "Oh", "a", "cookie!" ]
Common use case
If you leave the separator blank, it will dissect each character.
var pieces = sentence.split("");
// [ "O", "h", " ", "a", " ", "c", "o", "o", "k", "i", "e", "!" ]
Notice that the spaces stay in the resulting array because they were not used as the separator.
