+ * 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).
+ *
+ * @static
+ * @memberOf _
+ * @category Collection
+ * @param {Array|Object} collection The collection to iterate over.
+ * @param {Function|Object|string} [predicate=_.identity] The function invoked per iteration.
+ * @param- {Object} [guard] Enables use as an iteratee for functions like `_.map`.
+ * @returns {boolean} Returns `true` if all elements pass the predicate check, else `false`.
+ * @example
+ *
+ * _.every([true, 1, null, 'yes'], Boolean);
+ * // => false
+ *
+ * var users = [
+ *   { 'user': 'barney', 'active': false },
+ *   { 'user': 'fred',   'active': false }
+ * ];

+ * // using the `_.matches` iteratee shorthand
+ * _.every(users, { 'user': 'barney', 'active': false });
+ * // => false
+ *
+ * // using the `_.matchesProperty` iteratee shorthand
