+ * Creates an object composed of the picked `object` properties. Property
+ * names may be specified as individual arguments or as arrays of property
+ * names. If `predicate` is provided it is invoked for each property of `object`
+ * picking the properties `predicate` returns truthy for. The predicate is

+ * @param {Function|...(string|string[])} [predicate] The function invoked per
+ *  iteration or property names to pick, specified as individual property
+ *  names or arrays of property names.
+ * @param {*} [thisArg] The `this` binding of `predicate`.
