Checks if `predicate` returns truthy for **all** elements of `collection`. Iteration is stopped once `predicate` returns falsey. The predicate is invoked with three arguments: (value, index|key, collection). **Note:** This method returns `true` for [empty collections](https://en.wikipedia.org/wiki/Empty_set) because [everything is true](https://en.wikipedia.org/wiki/Vacuous_truth) of elements of empty collections.
