# 2021

This year, I've been tinkering a lot with [Deno][deno] as a [TypeScript][ts]
runtime and have been really enjoying it. I'm hoping to write this year's AoC
solutions using it.

Specifically, here's my `deno --version` output:

    $ deno --version
    deno 1.16.3 (release, x86_64-unknown-linux-gnu)
    v8 9.7.106.5
    typescript 4.4.2

It looks like I'm also doing some of these in Nim.

    $ nim --version
    Nim Compiler Version 1.6.0 [Linux: amd64]
    Compiled at 2021-10-19
    Copyright (c) 2006-2021 by Andreas Rumpf

    git hash: 727c6378d2464090564dbcd9bc8b9ac648467e38
    active boot switches: -d:release

And I decided part way through to do some Rust.

    $ rustc --version
    rustc 1.58.0-beta.2 (0e07bcb68 2021-12-04)

Enjoy!

## Usage

Run these solutions like so from their respective directories:

    deno run --unstable --allow-all $DAY.ts

And the Nim ones like so:

    nim c -d:release -d:ssl --run day$DAY.nim

And Rust:

    rustc -O --out-dir build day$DAY.rs && ./build/day$DAY

And if you want to measure memory usage with Deno programs:

    mkdir -p build
    deno compile --output build/$DAY --unstable --allow-all $DAY.ts
    /usr/bin/time -v ./build/$DAY

Or for Nim programs:

    mkdir -p build
    nim c -d:release -d:ssl --outdir:build day$DAY.nim
    /usr/bin/time -v ./day$DAY

And similarly for Rust:

    rustc -O --out-dir build day$DAY.rs
    /usr/bin/time -v ./build/day$DAY
