/**
* 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.
*
* @since 0.1.0
* @category Collection
* @param {Array|Object} collection The collection to iterate over.
* @param {Function} predicate The function invoked per iteration.
* @param- {Object} [guard] Enables use as an iteratee for methods like `map`.
* @returns {boolean} Returns `true` if all elements pass the predicate check,
* else `false`.
* @example
*
* every([true, 1, null, 'yes'], Boolean);
* // => false
