API

all(iterable, test = Boolean) -> Iterator

• iterable: an Iterator — a generator instance, Array, Map, String, or Set
• test: A function taking xs and returning a boolean value.

Returns true if all elements matched test, or false if any element failed.

Stops consuming elements from iterable as soon as they fail test.
