Please don't, `__proto__` is great if not abused. Swapping out the prototype of
an object is extremely useful.
function MyEventEmitter () {
EventEmitter.call(this)
}
MyEventEmitter.prototype.__proto__ = EventEmitter.prototype
Extremely easy inheritance and you don't have to mess with the constructor
property etc. Also allows you to do cool things with the default constructors
without messing with their prototypes.
var superArrayProto = { forEach : myCustomForEachFunction }
superArrayProto.__proto__ = Array.prototype
function makeSuperArray (arr) {
arr.__proto__ = superArrayProto
return arr
}
var superArray = makeSuperArray([])
(myCustomForEachFunction === superArray.forEach) // true
