What do the forward slahes in code do

So I looked up how to remove punctuation from a ruby string, and it looks like string.gsub(/[^a-zA-Z ]/, '') was the magic ticket, the thing I don't understand is what role the two foward slashes play in this role, as I found this online and played around with it and it seems that everything was centered around them being there. Any advice would be greatly appreciated. Thanks.
