simple-state

A state manager which is easy to use and dispose the variable at your ease. A simple Observable at best. It based on callback approach, where we can provide subscriber for the state variable. A lightweight library with no additional burden on your network.

Creating a 'state'

var timeState = new StateManager(); While creating a simple state we can pass a preset value for the variable.
----------------------- Accessing current value -----------------------
var timeState = new StateManager('New Value'); timeState.value() // returns 'New Value'
In order to access the current value of state we can use timeState.value().
--------------- Changing values ---------------
In order to change value, we can use the next method available in the State variable.
timeState.next('Changed value');
------------------- Subscribing changes -------------------
We can provide a subscriber function callback with arguements as Old Value, New Value. The subscriber function gets called when there is a change in value of the 'State'.
timeState.subscribe(function(oldState, newState){ console.log("Old Value >> ", oldState, " New Value >> ", newState); });
--------------------------------- Unsubscribing subscriber function ---------------------------------
'Subscribe' method will return an object with 'dispose' method available. We can use the dispose method to remove the subscriber function.
var temp = timeState.subscribe(function(oldState, newState){ console.log("Old Value >> ", oldState, " New Value >> ", newState); }); temp.dispose(); // removes the subscriber method
This is just the initial build, please be happy to contribute.
