+ * Checks if `predicate` returns truthy for **all** properties of `object`.
+ * Iteration is stopped once `predicate` returns falsey. The predicate is
+ * invoked with three arguments: (value, key, object).
+ *
+ * **Note:** This method returns `true` for
+ * [empty objects](https://en.wikipedia.org/wiki/Empty_set) because
+ * [everything is true](https://en.wikipedia.org/wiki/Vacuous_truth) of
+ * elements of empty objects.
+ *
+ * @since 5.0.0
+ * @category object
+ * @param {Object} object The object to iterate over.
+ * @param {Function} predicate The function invoked per iteration.
+ * @returns {boolean} Returns `true` if all properties pass the predicate check,
+ *  else `false`.
+ * @example
+ *
+ * everyValue({ 'a': 0, 'b': 'yes', 'c': false }, Boolean)
+ * // => false
