Comparing performance of: jquery 2.2.4 vs 2.1.1

Testing a functional programming method 'pluck'. This is an in-progress test. Taken from lodash source code, using the Array constructor to make an Array of a specified length, seems to have a considerable impact on performance. In my simple pluck implementation, not using the constructor e.g. const plucked = [], was considerably slower.
