Ruby programming !sort

I was searching for a quick way to sort objects in Ruby and I found this ingenious method online.

deviceArray.sort! {|a,b| a.getName.downcase <=> b.getName.downcase}

notes

deviceArray : an array of objects of type device

downcase : only needed if sorting alpa numerically or can use upcase
