Traits.js Robust Object Composition and High-Integrity Objects for ECMAScript 5

This paper introduces traits.js, a small, portable trait composition library for Javascript. Traits are a more robust alternative to multiple inheritances and enable object composition and reuse. traits.js is motivated by two goals: first, it is an experiment in using and extending Javascript's recently added meta-level object description format. By reusing this standard description format, traits.js can be made more interoperable with similar libraries, and even with built-in primitives. Second, traits.js makes it convenient to create "High-integrity" objects whose integrity cannot be violated by clients, an important property in the context of interaction between mutually suspicious scripts.
