Is there a way to write plugins (custom methods) for this? about store HOT 3 CLOSED

Yeah, there is store._.fn(name, fn), and there are plugins here you can use as examples: https://github.com/nbubna/store/tree/master/src

Adding a plugin function using the _.fn function, ensures that your plugin is available on all store interfaces, including those already created (e.g. store.session and any namespaces). That said, the functions in your plugin are already covered by this library:

• store.remove(key) already does what your pull does exactly, though i realize now it isn't documented: https://github.com/nbubna/store/blob/master/src/store2.js#L171
• store.has(key) is documented, but checks for key existence, not just undefined: https://github.com/nbubna/store/blob/master/src/store2.js#L101

Nonetheless, if you want the name "pull" or an "isUndef" function as plugins, i would write them something like this:

(function(_) {
  // create "pull" alias for remove
  _.fn('pull', function(key) {
     return this.remove(key);
  };
  // create fn to check for undefined values
  _.fn('isUndef', function(key) {
     return (typeof this.get(key) !== 'undefined');
  };
})(window.store._);

I'm going to leave this open, if you don't mind, as a reminder to add a little plugin documentation and update the doc for remove to point out that it returns any removed value.

Alright, i updated the README to say that remove returns removed data and add a simple extension example. Thanks!

Thanks for the info, you even went ahead and converted my code!
