traits.js: Robust Object Composition and High-integrity Objects for ECMAScript 5
Abstract
This paper introduces traits.js, a small, portable trait
composition library for Javascript. Traits are a more robust
alternative to multiple inheritance 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
