Great video! I'd love to see more like these, focused on just Ruby (not rails).

same goes for %S, and there are probably others

%W can use any delimiter you like, not just "/". it could be %W[ ... ], etc

using global methods is not required to use the bang! methods.
string.strip! works just fine

gsub = "global substitute" (replaces globally) sub = "(local) substitute)"

Nicely done! It's always good to be reminded of/introduced to methods like these.

@mikestok right you are - the += is a little misleading. This would probably have been a better example:
sum = scores.inject(0) {|sum, value| sum + value}
Good catch!
Mike Stok said
In the explanation of inject using bowling scores in a season it seems redundant to use sum += value at the end of the inject block as the inject will put the return value of the block into the "accumulator", so
sum = scores.inject(0) do |accumulator, score| accumulator + score end
works and might give more insight into how inject works.
