I've never used this pattern in Javascript, but it's somewhat common in Python because of how handy the dictionary.get() method is. A few problems TFA solves in JS are much easier with .get(), like defaults and false values.

Plus the fact that python doesn't have a switch statement so you kind of have to use a dict if you want that functionality without a long chain of if/elif/else.
