I don't see enough mention of this, but if you want immutability (to make shouldComponentUpdate easy) icepick is a better choice than Immutable.js for a great many applications: https://github.com/aearly/icepick https://github.com/aearly/icepick It's tiny but offers a number of utilities that are more convenient than what you get with ES6 spread syntax. The tradeoff with Immutable.js is that if you have huge single objects (arrays with many elements, objects with many keys), then making copies will get more expensive than with Immutable. Otherwise, icepick is all win.
