split a string in Ruby

str = "hello world"

str.split(" ")

This code uses the split method to split a string into separate words. The str variable holds a string of "hello world", which we want to split. The split method takes one argument, which is the character you want to split the string by. In this case, it’s a space, so the argument is " ".

When the code runs, the split method splits the string into two parts: "hello" and "world". It then puts each of those in an array and returns that array. So the end result is ["hello", "world"].
