In which the author addresses the claim, made in the new O'Reilly book 'Data Structures and Algorithms in JavaScript', that 'it is not possible to [implement Mergesort as a recursive algorithm] in JavaScript, as the recursion goes too deep for the language to handle'.

Being an attempt to write a computational fluid dynamics simulation using no more than two raised to the power ten bytes.

First, before I begin, N.B: apparently the extreme brevity required by this project has put me in rather a garrulous mood, so I apologize for the length of this post-mortem. If you’re interested in maybe learning a few byte shaving tricks for your own js1k, though, read on. Also, verbose variable names will be used for the sake of clarity, though keep in mind that all variables here have a single letter identifier in the final program.
