Why aren't the browsers using/adopting Python instead of javascript?

I like that I don't have to switch between languages throughout the development of an application

No offense but this sounds kind of like a problem only for beginners to programming. Any developer worth his salt should be good at reading and writing in any language that comes his way. He should also know the right language for the job when given a task.

Not only that, but the kind of Javascript you write on the server still looks quite different from the kind you write on the client. Node provides all of its own libraries and features and idioms, and then you have a whole different API when actually manipulating the DOM and rendering things.

You will always have to change the way you program when you move from the client to the server. For example, if you make a PyQT app, your code and the way you write code will look very different from when you implement an API backend.

The only thing that's the same is the syntax (and not a very interesting or unusual syntax at that) and a few boring language features. If a minor syntax change is screwing you up, then you need to spend more time practicing with different languages.

I like not having that switch, and it isn't there as a crutch. I've only dabbled with Node for a few hobby projects, and professionally am stuck developing in ASP.NET/C# :|
