array-of-truths
Ensure your input becomes an Array, and keep only the truthy values.
API
This module exports one function that holds another function:
arrayOfTruths(x)
If x is not an array, it will be treated as an array with x as the only item. Return a new Array that contains the truthy items from x.
.ifAny(x)
Like arrayOfTruths(x) but if there are no truthy items,
instead of an empty array, return number 0.
.ifAnyMap(x, m)
Map a list x through one or more mapper functions m
(function or array of functions), except initially and also
after each step, false-y items are removed from the list.
If the list would be empty, return number 0 instead.
