#### [] vs Array.new

```
Warming up --------------------------------------
           Array.new   238.371k i/100ms
                  []   336.249k i/100ms
Calculating -------------------------------------
           Array.new      6.298M (± 1.0%) i/s -     31.465M in   5.014660s
                  []     14.157M (± 0.8%) i/s -     70.612M in   5.004166s
                   with 95.0% confidence

Comparison:
                  []: 14157286.9 i/s
           Array.new:  6297668.8 i/s - 2.25x  (± 0.03) slower
