It seems you and I share a common interest in JavaScript details :-)
Here are some slides of mine (in English) about prototypal inheritance. The conference video is not in English unfortunately, but you may still find the slides interesting:

Thanks for this awesome article! I just started to use ES6 classes and found part 3 especially helpful.

Sorry for the late reply. Yes, the constructor property can be an alternative.
But ES2015 provides a very useful special symbol @@hasInstance, which allows to customize how instanceof works.
Please see [this chapter] for more details.

Awesome article! I was always wondering what the new "Symbol" was all about. Your article made it perfectly clear to me!

Thanks @analognico:disqus! I find Symbols pretty interesting too, especially to hack into JavaScript 😇.

`simpleObject.prototype` on Chrome 58.0.3029.110 now returns `undefined`.

In first example:

var obj = {};
str.constructor === Object // => true

it should be:

var obj = {};
obj.constructor === Object // => true
