News roundup: Modern JavaScript, V8Monkey and SpiderNode, Adapt.js

Modern JavaScript

Modern JavaScript by Rebecca Murphey makes the case that we still have a ways to go in the JavaScript community in terms of dependency management, cross-code communication, and modularity of code, and argues in support of the AMD proposal (Asynchronous Module Definition API). In short, she makes the case that we haven’t found a good way to make everything in the JavaScript landscape play nicely with each other yet. At least in an ideal fashion.

V8Monkey and SpiderNode

Mozilla has taken an interest in Node and is starting to fashion its own flavor using their own JavaScript engine.

You may remember concerns a few months back about Node’s tight coupling to V8, the engine that powers Google’s Chrome browser. Paul O’Shannessy, a Mozilla engineer, echoed the same concern and also explained it as a rationale to build a V8 API on top of Mozilla’s own JavaScript engine SpiderMonkey, resulting in what they call V8Monkey. SpiderNode, on the other hand, is the general term for Mozilla’s fork of Node.

Earlier this week, it looks like they were successful in getting Node to run on V8Monkey briefly before segfaulting. Progress, but there’s more work to be done!


Adapt.js is a very lightweight JavaScript file that determines which CSS to load before a browser renders a page, as well as after a window resize (which also occurs on screen rotation on mobile devices). It serves as an alternative to building a separate website for mobile or serving content with media queries (which aren’t universally supported, requiring a polyfill for older browsers).
