/prog/ - I hate javascript

Currently I am learning how to program windows 8 metro apps using Javascript.

I have some prior experience with javascript, but only with the stuff js was actually designed for: small snippets embedded in HTML code. This is the first time I am developing a complete application in js. And I got to say: the more I learn about it the more I hate it.

-no type safety
-all errors except for the most trivial syntax errors can only be found at runtime when the code in question is executed
-a mistyped member variable of an object, is even silent at runtime, because you needn't declare public member variables of classes, even when using 'use strict'.
-OOP is a joke. Most features which should be standard repertoire of an OOP language are only available through nasty hacks. Most annoying flaw so far: event handlers can't call instance methods*. wtf? how am I supposed to create a proper MVC pattern, when my controllers can't be instanced?

Why do people keep promoting this shit? Sure, you do everything nowadays in a webbrowser, and in a web application, javascript is the only standardized, platform-independent way to have any logic in the client. So you don't get around using JS when you have a web application. But why do people promote this abomination of a language for areas where much more viable alternatives exist? Like stand-alone client applications (windows 8 metro apps) and even server applications (NodeJS).

*They can call them, but they are executed in a static context, not the context of the object, which means that you can't access any member variables.
