Tip for @peterc's ruby trickshot

gistfile1.rb

# Two tips: 

# Initialize a Hash with a default value of Array.  
    hash = Hash.new {|hash,key| hash[key] = []}
    hash["some-key"] << "some-string value"
    
    pp hash
#    => {"some-key"=>["some-string value"]}

----------------------------------------------------------

# Sort a hash by key.
  hash = {"a" => "a-value", "c" => "c-value", "b" => "b-value"}
  Hash[hash.sort]
#  => {"a"=>"a-value", "b"=>"b-value", "c"=>"c-value"}

# They are simple but incredibly useful.

I already had the first but am loving the second! I shared it on the book's Twitter account already but will be sure to include and credit you.

Awesome. Glad it was helpful. As an aside I really liked the screencast you did for ruby trick shots (especially Array#zip). Keep it up.
