Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

none
Returns true if the provided predicate function returns false for all elements in a collection, false otherwise.
Use Array.prototype.some() to test if any elements in the collection return true based on fn.
Omit the second argument, fn, to use Boolean as a default.
const none = (arr, fn = Boolean) => !arr.some(fn);
none([0, 1, 3, 0], x => x == 2); // true
none([0, 0, 0]); // true
