Converting nested array to flat hash

Question

I have this:

[["hello", 1], ["world", 1]]

I want this:

{ "hello" => 1, "world" => 1 }

I've coded something that WORKS, but feels stupid. Here it is:

hash = {}
array.each do |element|
  hash[element[0]] = element[1]
end 
hash

Is there a better way?

Hash[[["hello", 1], ["world", 1]]] # =>  => {"hello"=>1, "world"=>1}

If you are in Ruby2.1 use Array#to_h

[["hello", 1], ["world", 1]].to_h
