Dave Herman put together a repository showing a real program, adapted from array comprehensions: https://github.com/dherman/sudoku/blob/master/solver.pythonic.js to using methods called .lazy(), .concat(), .map(), .filter(), and .flatMap(): https://github.com/dherman/sudoku/blob/master/solver.methods.js but I don't understand what's going on there. Where are these methods defined? Is it intended that .map() and .flatMap() will be defined on all iterables? If so, how? Didn't the committee also decide not to give Iterables or Iterators a common prototype, or define these methods as part of the Iterator or Iterable interface?
