obj-extend
When called, this module simply sets all of the properties of each source object onto the destination object (the first argument). Every property with the same name is overridden in the order in which they were passed.
Installation
$ npm install obj-extend
Usage
var events = require('events');
var extend = require('obj-extend');
var Person = function (name) {
this.name = name;
};
extend(Person.prototype, events.EventEmitter.prototype, {
emitName: function () {
this.emit('name', this.name);
}
});
