# compare

ReasonML helpers for generating cmp functions.

## Usage

```reason

module Comparator =

  Belt.Id.MakeComparable({

    type t = string;

    let cmp =

      Compare.concat([

        Compare.by(key => key),

        Compare.by(key => String.length(key)),

      ]);

  });

type t = Belt.Map.t(Comparator.t, int, Comparator.identity);

let ourMap = Belt.Map.fromArray(~id=(module Comparator), [|

  ("a", 1), ("b", 2), ("ab", 3)

|]);

Belt.Map.forEach(ourMap, Js.log2);

```
