# 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 1.16.3 (release, x86_64-unknown-linux-gnu)
    v8 9.7.106.5
    typescript 4.4.2

Enjoy!

**EDIT**: Since performance is not what I would like, it looks like I'm also doing some of these in Nim.

**EDIT 2**: I sprinkled some zig in there. I've been meaning to mess with it for a while.

## Usage

Run these solutions like so:

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

And the Nim ones like so:

    nim c -d:release -d:ssl --run $DAYMODULE.nim

And the Zig ones like so:

    zig build-exe -O ReleaseFast 6.zig -femit-bin=build/zig-$DAY
    ./build/zig-$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 $DAYMODULE.nim
    /usr/bin/time -v ./$DAYMODULE

Or for Zig programs:

    mkdir -p build
    zig build-exe -O ReleaseFast 6.zig -femit-bin=build/zig-$DAY
    /usr/bin/time -v ./build/zig-$DAY
