Immutable.js Diff

High Fidelity diffs for Immutable.JS objects

Forked from immutable-diff which focuses more on RFC 6902 style patches, requiring string values for the paths.

Changes from immutable-diff:

• op.path is now an Immutable.List rather than a patch style path, usable for .updateIn
• Support for complex values as keys
• null & undefined are considered separate values
• Babel/ES6 codebase

API:

diff(a, b)

Creates a diff between a and b

var Immutable = require('immutable');
var diff = require('immutable-diff');

var map1 = Immutable.Map({a:1, b:2, c:3});
var map2 = Immutable.Map({a:1, b:2, c:3, d: 4});

diff(map1, map2);
// List [ Map { op: "add", path: ["d"], value: 4 } ]

var map1 = Immutable.Map({a:1, b:2, c:3});
var map2 = Immutable.Map({a:1, b:2, c:3, d: 4});
