==Perhaps a specific task ?==
It can help comparison across languages if there is a specific task with a readily intelligible motivation.
One candidate might be to:
# Create and compose safe versions (number -> Maybe number) of 3 partial functions (reciprocal, sqrt, log)
# Show the results of applying the required composition to a specific set of input values. In the ES5 JavaScript example, I have used, for instance [-2, -1, -0.5, 0, 1 / Math.E, 1, 2, Math.E, 3, 4, 5]
