Data props diffing in a React component and re-initialize a cell of jQuery object without re-initializing jQuery grid object in the componentDidUpdate method (and without re-rendering the whole React component). Code snippet in blog post http://andrejgajdos.com/how-to-avoid-refactoring-in-your-first-react-application/
let diff = require('immutablediff');
shouldComponentUpdate(nextProps, nextState) {
let propsDiff = diff(this.props.data, nextProps.data);
if (propsDiff.size === 1) {
let operation = propsDiff.get(0).get("op");
let replacedObj = propsDiff.get(0).get("value");
switch (operation) {
case "replace":
if (Immutable.Map.isMap(replacedObj)) {
