Created November 15, 2021 09:59
Convert a Uint8Array to base64.
/**
* There's no real reason to use this. Buffer is available in node:
*
* Buffer.from(typedArray.buffer).toString('base64');
*
* and the browser has atob/btoa (which are fine to use for the ascii
* characters used to represent bytes.

Conway's Game of Life. I put this together quickly as something to iterate on as a generative art project.

// Usage: node advent-of-code-2017-d04p2-boring.js /path/to/input.txt
// This boring version works by lexicographically sorting the characters
// in each word of the pass phrase, and then adding them all to a set.
// If the size of the set is less than the number of words in the
// passphrase, then at least one pair of words were anagrams of each
// other and the passphrase invalid.
