Usage

var diff = require('diff-list');

var transforms = diff(srcRows, dstRows, {key: 'id'});

returns {put: [..], post: [..], del: [..]} transformations needed to be applied to src to obtain dst, not taking into account ordering.

Options

• equal
  function of two parameters that returns true if they are equal,
  defaults to strict deep-equal.
• key
  check if an item having that key already exists (put) or is new (post).
