Oolong.js

Oolong.js is a library for JavaScript full of object-related utilities. It's similar to Underscore.js, but it focuses strictly on functions dealing with objects. It's implementation emphasizes simplicity and good taste. For example, it always takes inherited properties into account leading to less surprises for users of your code.

Oolong.js grew out of my frustration with Underscore.js and Lodash.js and their inconsistent and sometimes outright ignorance of inherited properties. This leads to unnecessary complexity, arbitrary constraints and a leaky-implementation in your code or public APIs. This behavior is cancer propelled around by ignorance and misunderstandings between dictionaries and interfaces. Oolong.js is my first step at killing it.

Installing

npm install oolong

Oolong.js follows semantic versioning, so feel free to depend on its major version with something like >= 1.0.0 < 2 (a.k.a ^1.0.0).
