Advent of Code

2020 uses node.js and 2021 uses deno.

Prerequisites

new: use deno

❯ deno --version
deno 1.16.3 (release, x86_64-apple-darwin)
v8 9.7.106.5
typescript 4.4.2

node >= 12

From project root:

yarn run:<mode> <day> <part>

where:

Navigate to a day

$> cd 2020/day1

then run node:

$> node .

Since each day has 2 problems, there will either be 2 outputs or a commented out section for part 1 or part 2.

Each prompt is linked in the solution header.
