+# EvEmitter
+
+_Lil' event emitter_ — add a little pub/sub
+
+EvEmitter adds publish/subscribe pattern to a browser class. It's a smaller version of [Olical/EventEmitter](https://github.com/Olical/EventEmitter). That EventEmitter is full featured, widely used, and great. This EvEmitter has just the base event functionality to power the event API in libraries like [Isotope](http://isotope.metafizzy.co), [Flickity](http://flickity.metafizzy.co), [Masonry](http://masonry.desandro.com), and [imagesLoaded](http://imagesloaded.desandro.com).
+
+## API
+
+``` js
+// Inherit prototype, IE8+
+MyClass.prototype = new EvEmitter();
+
+// Inherit prototype, IE9+
+MyClass.prototype = Object.create( EvEmitter.prototype );
+
+// Mixin prototype
+_.extend( MyClass.prototype, EvEmitter.prototype );
+
+// single instance
+var emitter = new EventEmitter();
+```
+
+### on
+
+Add an event listener.
+
+``` js
+emitter.on( eventName, listener )
+```
+
++ `eventName` - _String_ - name of the event
++ `listener` - _Function_
+
+### off
+
+Remove an event listener.
+
+``` js
+emitter.off( eventName, listener )
+```
+
+### once
+
+Add an event listener to be triggered only once.
+
+``` js
+emitter.once( eventName, listener )
+```
+
+### emitEvent
+
+Trigger an event.
+
+``` js
+emitter.emitEvent( eventName, args )
+```
+
++ `eventName` - _String_ - name of the event
++ `args` - _Array_ - arguments passed to listeners
+
+## Code example
+
+``` js
+// create event emitter
+var emitter = new EventEmitter();
+
+// listeners
+function hey( a, b, c ) {
+  console.log( 'Hey', a, b, c )
+}
+
+function ho( a, b, c ) {
+  console.log( 'Ho', a, b, c )
+}
+
+function letsGo( a, b, c ) {
+  console.log( 'Lets go', a, b, c )
+}
+
+// bind listeners
+emitter.on( 'rock', hey )
+emitter.once( 'rock', ho )
+// trigger letsGo once
+emitter.on( 'rock', letsGo )
+
+// emit event
+emitter.emitEvent( 'rock', [ 1, 2, 3 ] )
+// => 'Hey', 1, 2, 3
+// => 'Ho', 1, 2, 3
+// => 'Lets go', 1, 2, 3
+
+// unbind
+emitter.off( 'rock', ho )
+
+emitter.emitEvent( 'rock', [ 4, 5, 6 ] )
+// => 'Hey' 4, 5, 6
+```
