Last year I started playing around with using memoized private helper methods in my controllers instead of the traditional instance variable assigns we see in RoR controllers. Here's an example:

class PostsController < ApplicationController
  helper_method :new_post, :post, :posts
  
  def new; end
  def show; end
  def edit; end
 def index; end

for-of, early termination, iterators, and generators

If we terminate a loop early, for-of invokes method .return() of the iterator. Generators return generator objects (that implement both the Iterable interface and the Iterator interface). If we invoke .return() on such an object, the generator is terminated. We can prevent that by overriding .return().

Demonstration:
