A JavaScript partial port of the excellent Python dictdiffer module. We only had the need to support one-way updating (Python -> JavaScript) so we only implemented the patch() method. Feel free to issue PRs if you are interested in implementing any of the other methods from the Python module.
/**
* This function will take a patch (diffResult) object, as defined by the Python
* dictdiffer module:
* https://dictdiffer.readthedocs.io/en/latest/
* and will patch the destination JavaScript object. This is very useful when sending
* changes to objects shared between Python code and JavaScript code, like through a
* websocket connection.
*
* @param {object} diffResult - the output from the Python function dictdiffer.diff()
* @param {object} destination - the target JavaScript object. Note that prior to changes
* the dictionary on the Python side must match the JavaScript
* object. It is a one-way patch
* (Python dict -> JavaScript object).
* @returns {object} - returns the patched object. While not strictly necessary because the
* destination object is directly updated, it's useful to return the
* object in some scenarios.
