split

The split method is the opposite of join. While join combines the elements of an array into a string, split divides a string into an array. Like join, split takes an optional argument: the delimiter. The delimiter is a string along which split divides the receiver string. Whatever string you use as the delimiter will be omitted from the returned array. By default, the delimiter is an empty space (' '). The split method does not modify the original string.

proposition_one_point_two = "The world divides into facts."
proposition_one_point_two.split #=> ["The", "world", "divides", "into", "facts."]
proposition_one_point_two.split(' ') #=> ["The", "world", "divides", "into", "facts."]
proposition_one_point_two.split('d') #=> ["The worl", " ", "ivi", "es into facts."]
proposition_one_point_two.split('.') #=> ["The world divides into facts"]
proposition_one_point_two.split('')  #=>["T", "h", "e", " ", "w", "o", "r", "l",
                                     #    "d", " ", "d", "i", "v", "i", "d", "e",
                                     #    "s", " ", "i", "n", "t", "o", " ", "f",
                                     #    "a", "c", "t", "s", "."]

# the original string is not modified
proposition_one_point_two #=> "The world divides into facts."
