First impressions of JavaScript, from an old timer coming from Java/C#

It's interesting. There are no classes (exactly) or Main() method. Just put that code anywhere. Just create random global variables of some mysterious type that is at the same time no type and every type. Tack on random properties and methods anywhere and everywhere at your whim. Classes are implemented as functions and functions within functions. Everything works differently, yet it still manages to emulate object oriented programming effectively to some degree. JavaScript, you're not replacing my C#, but I was doubtful and yet you've managed to impress and intrigue me. You have evolved, and I'm having fun with you. <-- my ode to an inanimate programming language
