Node.js and MongoDB Turning JavaScript Into a Full-Stack Language

Nerval's Lobster writes "For all its warts and headaches, JavaScript has emerged as the lingua franca of the modern Web, arguably second in adoption only to HTML itself, which obviously is just a markup standard rather than a full-fledged programming language. It's effectively impossible to launch a sophisticated Web project without making extensive use of JavaScript and AJAX dynamic loading. That's precisely why recent projects that move JavaScript beyond its usual boring domain of defining in-browser interactivity are so interesting — because it's already dominant, and growing even more so. Writer and software developer Vijith Assar argues that Node.js and MongoDB are turning JavaScript into a full-stack language. 'In the grand scheme, Node and Mongo are still quite new; for the most part, ace JavaScript developers who can write brilliant code on both sides of the request transaction have yet to emerge,' he suggests. 'But if and when they do, the things they build could be jaw-dropping.'"

Can any real developer explain why having a javascript backend would be any different to any other backend in such a way where something jaw-dropping could only be the result of the javascript backend?
The quote that you referenced is pure hyperbole--in fact, it is bordering on bullshit. There's nothing a javascript backend can do that a Ruby, Python, Perl or whatever backend cannot. However, it sure would reduce cognitive load to not switch languages between browser and server ends. Personally, I've always liked Ruby (and Python before it) very much, and I like Ruby on Rails. But I'm watching node.js for this very reason--no matter how elegant RoR wraps up the process of sending dynamic javascript over to the browser for execution, it's still butt-ugly and an all-around pain to be switching between two languages, especially on such a small scale. It's not like when I switch from web dev one day (or preferably, week) to native client--sometimes it's Ruby for a minute then javascript for a minute then back to Ruby. Anybody who thinks that is not affecting their productivity is just not paying attention ;-)
