    Map Or Similar

    Returns a JavaScript Map() or a similar object with the same interface, if Map is not available. Focuses on performance. No dependencies. Made for the browser and nodejs.

    Install

    npm install map-or-similar --save

    Use

    var MapOrSimilar = require('map-or-similar');
     
    // make a new map or similar object
    var myMap = new MapOrSimilar();
     
    // use it like a map
    myMap.set('key1', 'value1');
    myMap.set({ val: 'complex object as key' }, 'value2');

    The following methods and properties are supported identically to Map():

    set(key, val)     : Sets a value to a key. Key can be a complex object, array, etc.
    get(key)          : Returns the value of a key.
    has(key)          : Returns true if the key exists, otherwise false.
    delete(key)       : Deletes a key and its value.
    forEach(callback) : Invokes callback(val, key, object) once for each key-value pair in insertion order.
    size              : Returns the number of keys-value pairs.

    Does not support other Map methods or properties.
