General Development Opa, the new open source programming language for web applications, just released its 0.9.0 'S4' version. Opa is a single programming language for specifying client code, server code and database code. The new release introduces two major features: A new default syntax that resembles JavaScript and was asked for by the community, and an abstraction layer for the NoSQL database MongoDB. Features that were previously supported by the internal Opa database are now available with the fast-growing, scalable NoSQL database. Together, Opa and MongoDB, provide a way to develop complex web applications and have them scale out easily. Many other smaller features have been added, as the number of contributors to the code on github grows.

Javascript has no type verification.
Which probably results with more debugging or more bugs.

Opa has a syntax similar to Javascript.
Opa is designed from scratch for the job and provides integrated high-level constructions that are very handy (html, slicing, db ...).
It means you can focus on your application and partly forget about AJAX, escaping, comet and other boring stuff.

ps : I am working on Opa

I would really like to study OPA in the future.
I am unfortunately one of those guys that need "how to do" manuals.
Not just those "how to program" type books but actual applications, "by example" books.
In php for example you get cookbooks, how to program a shopping cart, blog, cms ect.
Hope we'll see books like this for OPA in future.

I would like to delve into this in the future.
Having to learn just one language for site development is very alluring.

The main problem I have with these things that "ALL" of my code is tied into your language.

I have enough problems with just with all our current code relying on 3 blobs (dlls) from a 3rd party.

Also all the generated JavaScript appears to be jQuery.

15 seconds on one method when viewing your documentation. I use an 8 virtual processor (4 physical cores) Xeon Workstation and your documentation is bringing my PC to its needs in the latest firefox.

I am sorry but I couldn't recommend your framework.
