weakmap-shim

A minimal weakmap shim

Example

``js
var weakMap = require("weakmap-shim")

var map = weakMap()
var key = {}

map.set(key, 'some value')
var v = map.get(key) // 'some value'
`

create-store Example

`js
var createStore = require('weakmap-shim/create-store')

var store = createStore()
var key = {}

var value = store(key)

// value is weakly bound to key. value is a plain object
value.foo = 'bar'

var value2 = store(key)

var v = value2.foo; // 'bar'
var bool = value === value2; // true
`

Motivation

Benvie has an excellent weakmap
module that's far more robust. However it contains quite a bit
of loc.

- weakmap : 7451 bytes
- weakmap-shim : 2106 bytes
- weakmap-shim/create-store : 1311 bytes

This module is only worthwhile if you want to add a weakmap to
a small module (10 - 30 loc) and dont want to bloat it with
a heavier weakmap

Installation

npm install weakmap-shim`
