Hey!

This is started kit for working Advent of Code puzzle. You can clone it and build it with esy

git clone https://github.com/ManasJayanth/reason-aoc-starter
cd reason-aoc-starter
esy

To enable Flambda optimisations on your compiled binaries, use @release

Examples,

esy @release # to just build
esy start:release # to run flambda opt enabled binary

If you dont have esy already installed,

npm i -g esy
# or
yarn global add esy

@reason-native/console

Reason is a type safe language and functions have to be intentionally written in a way accept arguments of any type. Benefits of such strong typing is seen in large codebases, but for simple printing, one could need type specific printers like print_int etc.

@reason-native/console provided a familiar generic Console.log inspired by the browser's console.log. See here

Console.log("Some string here");
Console.log(true);
Console.log(Some("hi"));
Console.log(None);
