# I've got a hash of things, that all contain an object with in them that has a score property.
# how to pull out the one with the highest score?

things = {
  :foo => {
    :score => 50
    # other props
  },
  :bar => {
    :score => 30
    # other props
  },
  :baz => {
    :score => 66
    # other props
  }
}

you probably want to look at Enumerable - http://ruby-doc.org/core-2.0/Enumerable.html#method-i-max

// array = your array of objects
// o = an object in the array

Math.max.apply(Math,array.map(function(o){return o.y;}))
