JarCastingweakmap-shim
A minimal weakmap shim
Example
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
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 bytesweakmap-shim: 2106 bytesweakmap-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
