hash.js is a simple way to safely use a JavaScript object as hash.

Fast: Usage of a regular object as the hash

Safe: Any key can be used. Keys with names that start with "" are internally escaped to circumvent the mess that JS implementations induce with "magic" properties like proto, count, parent__

Installation

npm install hash

Example in node.js

var hash = require('hash')

var existingDataWithEscapedKeys = { : 1, b: 2, 'parent__%': 3 }

var myHash = new hash(existingDataWithEscapedKeys / optional /)

myHash.set('a', 123) myHash.set('proto', 'value')

myHash.get('parent') // 3 myHash.get('a') // 123 myHash.get('proto') // 'value'

myHash.has('constructor') // false

myHash.del('a')

myHash.get('a') // undefined

myHash.del('parent')

myHash.getData() // { : 1, b: 2, 'proto__%': 'value' }

myHash.forEach(function iterator (value, key) {

// ...

} /, optionalThisArg /)
