deep6 is a no-dependency ES6 mini-library:

• Advanced deep equivalency for JavaScript structures.
  • Extensible to accommodate custom objects.
• Traversing objects.
  • Extensible deep cloning.
• Written in ES6:
  • Use it in Node or browsers without transpiling.
  • Natively supports Map, Set, typed arrays.
  • Natively supports symbols and property descriptors.
  • Provides CommonJS modules for convenience.
• Unification.
  • Identifying and capturing object fragments.
• Efficient non-recursive algorithms.
  • ~500 tests to ensure correctness.

The library is written as a collection of ES6 modules. For convenience, and to support older versions of Node, it provides a collection of CommonJS (require()-style) modules as well.

Background

It is the next generation of heya-unify, which basic concepts were explained and demonstrated in the following blog posts:

• Unification for JS.
• When to unify in JS.
• heya-unify: custom unification.
• heya-unify: incomplete objects.
• heya-unify: back to JS.
