Converting upper-case string into title-case using Ruby

Question

I\'m trying to convert an all-uppercase string in Ruby into a lower case one, but with each word\'s first character being upper case. Example:

convert \"MY STRING HE

Answer 1

string = "MY STRING HERE"
string.split(" ").map {|word| word.capitalize}.join(" ")

The way this works: The .split(" ") splits it on spaces, so now we have an array that looks like ["my", "string", "here"]. The map call iterates over each element of the array, assigning it to temporary variable word, which we then call capitalize on. Now we have an array that looks like ["My", "String", "Here"], and finally we turn that array back into a string by joining each element with a space (" ").
