ruby convert array of delimited strings into hash

Question

I have an array

["bob:12 elm st", "sally:100 digital ave", "tom:2324 elmhurst st"]

which I need to convert to

{"bob" => "12 elm st", "sally" => "100 digital ave", "tom" => "2324 elmhurst st"}.

I know I can do

array.each do |e|
  k = e.split(":").first
  v = e.split(":").last
  hash[k] = v
end

Is there a more elegant way to do this?

Hash[] constructs a hash from array.

Hash[array.map {|el| el.split ':'}]

I believe ruby 2.1 has a .to_h method.

Therefor,

array.map { |i| i.split ':' }.to_h

will work.
