cloning javascript event object

Question

Anybody know how to do a deep copy/cloning of a native javascript event object? I know I can create a new event object and set the appropriate properties manually to match

Answer 1

Inspired by Kofifus answer I just do that

function cloneEvent(type, event) {
    var evt = new Event(type);
    return Object.setPrototypeOf(evt,event);
}

or just

function cloneEvent(event){
  return Object.create(event)
} 

it returns a new object that protects you from edit the original object. but let you read and edit the property. thanks to js prototype chain
