Rescript JS Map

Rescript JS Map is a ReScript library that provides bindings to the JavaScript Map data type.

Installation

Using yarn or npm:

yarn add rescript-js-map

This package relies on the rescript-js-iterator package for Iterator bindings. In your bsconfig.json, add:

{
  "bs-dependencies": ["rescript-js-map", "rescript-js-iterator"]
}

Usage

module Map = Js_map
let map = Map.make()

let mutatedMap = map->Map.set("hello", "world")
let isPhysicallyEqual = map === mutatedMap // true
let hello = map->Map.get("hello") // Some("world")
let hasHello = map->Map.has("hello") // true
let foo = map->Map.get("bar") // None
let size = map->Map.size // 1
