No offense, but I seriously doubt that this will help any beginner. You simply cannot beat down something as complex as this to a few sentences and then expect folks who have never heard of JS before to actually understand anything of what you just said.
It simply won't work that way, you got to start from scratch and actually explain each and every aspect in detail, even the things that might seem easy to you. Also, you need a proper structure, you cannot just jump from one topic to another around if you'd like your readers to get your point. And if your readers do not get your point, this is nothing but a major waste of time for both them and you.
