Actually you don&#x27;t need to use React.createClass to use mixins, there is <a href="https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;react-mixin" rel="nofollow">https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;react-mixin</a> which implements them via decorators. Either I wouldn&#x27;t consider inheritance and mixins interchangeable.
