I think the vague answer is &#x27;use mixins&#x27;, but they are generally unsatisfying. One hopes that using ES6 classes to define react components this way would allow proper inheritance, but the whole ES6 thing is a mess that breaks a bunch of other things (notably autobinding this). Upshot is my code remains repetitive.<p>Where possible you can use composability, extracting common function into a subcomponent, but this doesn&#x27;t always make for neater code.
