// a function is just a function.  By default it has no 'this' and returns nothing
function myFunction() {
  this.value = 5;
}

// if I call it, I get nothing back
var obj1 = myFunction();  // obj1 is undefined

// if I call it with 'new', a new empty object is assigned to 'this' and returned to me afterwards
var obj2 = new myFunction();  // obj2 is { value: 5 }

The code in question looked like this (shortened version):

def count_of_beats_by_kind 
  set = @project.beats
  list = BEAT_KINDS
  list.each do |kind|
    counts[kind] = set.where(:kind => kind).count.to_f

return counts
