I'd say that the (probably overwhelming) majority of arrow functions
have a single parameter and, in those cases, the JS syntax saves four
characters, ignoring whitespace. Another way of looking at it is that
you have six characters of boilerplate with the fn() syntax versus two
in JS (ignoring whitespace) for single param arrow functions.
