Enterprise JavaScript -- Not the best idea

See this:

JavaScript is a swampy foundation for your enterprise codebase: My latest column at SD Times http://t.co/a82aUquk0d

The article lists reasons why Enterprise JavaScript is a recipe for disaster. "Finally, there's legacy integration..." This is the point.

In particular, JavaScript needs to get the data from somewhere: a backend process. If we push business knowledge into the front-end, even if we're assiduous about code libraries and sharing, we still have to fight with the "Out-Of-Date JS Library" issue. Server-side business knowledge is inherently consistent and sharable.

The big reason JavaScript feels good is because it's seems productive. Java is complex. C++, C#, and Objective C are Very Complex.

And.

Backend programming doesn't allow you to see finished-looking stuff right away. When you're fooling around with JavaScript you feel like you're doing real work. You're moving data around on the HTML page, that's productivity, right?

A spreadsheet is just as productive as JavaScript presentation.  Almost exactly as productive. The underlying data and processing still originates somewhere else. That's where the real value lies. In the data. In the backend.
