The Extensible Web Manifesto
Brendan Eich and several other important web people propose a new approach for evolving the web platform. Currently, it takes a long time to standardize features, after which they are implemented, used by developers and iterated based on developer feedback. In contrast, Eich et al. propose to focus on a foundation with secure and efficient low-level features. Higher-level features would be implemented in JavaScript.

Code and Libraries

Is.js: Check Your Strings Against Predefined Formats
Checks whether a string conforms to one of several predefined data formats. For example: is('0-85131-041-9', 'isbn') and is('1996-12-19T16:39:57-08:00', 'datetime') both return true. Other formats include credit card numbers, phone numbers and postal codes. Runs as a jQuery plugin, vanilla JavaScript or Node.js module.
