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 */)
