jmh-map

This is a general purpose key/value map.

Usage

var myCoolMap = Object.create(JmhMap);

myCoolMap.initMap('Used in a demo');

myCoolMap.put('Name', 'Value');
myCoolMap.put(2, 5);

console.log(myCoolMap.get('Name'); // Value
console.log(myCoolMap.get(2); // 5
console.log(myCoolMap.get(3); //_NOT_IN_MAP_

myCoolMap.remove('Name');
console.log(myCoolMap.get('Name');//_NOT_IN_MAP_

Main Usage

This is my goto data structure. Great for passing info during HTML redirects using sessions storage. Could also use local storage.

Session Storage

var myCoolMap, sessionObject;

function loadState()
{
  myCoolMap = Object.create(JmhMap);
  
  if(!sessionStorage.getItem('coolMap')) {
    //new empty map
    myCoolMap.initMap('Used in demo');
  } else {
    //init from object
    sessionObject = sessionStorage.getItem('coolMap');
    sessionObject = JSON.parse(sessionObject);
    myCoolMap.initFromObject(sessionObject);
  }
}

function saveState() {
  sessionStorage.setItem('coolMap', JSON.stringify(myCoolMap));
}

Advaced Usage

Note you can have maps inside of maps. You may store other complex objects that have both jmhObjectType property and initFromObject f(X).

TODO

1. Add check for initFromObject f(X) line 29
2. If object has a jmhObjectType would have its own objectToString() line 70

ES 6

If you are using es 6 you may want to use the new Map object https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map
