Unify: a unification tool with a deep equivalence and partitioning of objects.

It is thoroughly documented in series of blog posts:

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

If you plan to use it in your node.js project install it like this:

npm install heya-unify

For your browser-based projects I suggest to use volo.js:

volo install heya/unify heya-unify
