+/**
+ * Creates a slice of array excluding elements dropped from the end until predicate returns falsey.
+ * The predicate is invoked with three arguments: (value, index, array).
+ *
+ * @template T - The type of elements in the array.
+ * @param array - The array to query.
+ * @param [predicate] - The function invoked per iteration.
+ * @returns Returns the slice of array.
+ * @example
+ *
+ * const users = [
+ *   { user: 'barney', active: true },
+ *   { user: 'fred', active: false },
+ *   { user: 'pebbles', active: false }
+ * ];
+ *
+ * // Using function predicate
+ * dropRightWhile(users, user => !user.active);
+ * // => [{ user: 'barney', active: true }]
+ *
+ * // Using matches shorthand
+ * dropRightWhile(users, { user: 'pebbles', active: false });
+ * // => [{ user: 'barney', active: true }, { user: 'fred', active: false }]
+ *
+ * // Using matchesProperty shorthand
+ * dropRightWhile(users, ['active', false]);
+ * // => [{ user: 'barney', active: true }]
+ *
+ * // Using property shorthand
+ * dropRightWhile(users, 'active');
