Hash.new with array as default value
6/10/14 5:41 PM

Hi, I told several people in office hours something incorrect, so I am clarifying that now. I had said that you could use

Hash.new([0,0])

to create a hash table where missing keys would have a default value of [0,0]. This does not work as you might think. It just creates exactly one instance of an array, and returns it every time you index into the hash with a nonexistent key. The correct way to do this is to not use the shortcut. Instead, you would need to do it the regular, manual way, where when indexing into a hash, you first check if the key exists, and if not set it equal to [0,0].
