Returns true if the provided predicate function returns true for at least one element 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 any = (arr, fn = Boolean) => arr.some(fn);
any([0, 1, 2, 0], x => x >= 2); // true
any([0, 0, 1, 0]); // true
