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.'"
Anecdotally (having worked with node.js for the past year or so), whenever I've needed to do something not available in the core libraries, there has been an npm for it, usually several. But - and this is a rather big but - their maturity can vary quite a bit. The biggest issue really is documentation, that can be incorrect or completely out of date. Yes, there always is the source, but that's hardly ideal.
Having said that, in general I do like node.js. It takes some time getting used to and you have grasp Javascript well in order to use it efficiently, but if you're working with JSON data (we use CouchDB) it's quite a natural fit.
I was speaking to a friend of mine the other day, who said "Don't you find it bizarre that Javascript has become the assembly language of the web?"
And that's just it: I think javascript sucks, and I avoid it whenever possible. Instead I use CoffeeScript, which I find unobjectionable. Sure, it "compiles" into javascript - and I don't much care.
I pointed out that I never really learned assembly when I was cutting my teeth (decades ago), and so I really didn't care what was down there. It's kind of nice that I know enough Javascript to debug tricky issues when the need arrises.
I thought that coding in assembly sucked, too - still do. The higher the language, the more I tend to like it. Besides CoffeeScript, I'm keeping an eye on Dart.
So, yeah, it's bizarre that javascript has become the assembly of the web world. But it runs all over the place because it runs all over the place. Whatever. As long as there's something better to write code in than javascript, it doesn't bother me...
He was trying to say that its only twice as slow.
