What are React Mixins? in REACT

Practice



Mixins are a way to completely separate components so that they can share common functionality. Mixins should not be used and can be replaced with components or higher-order decorators .

One of the most commonly used mixins is

PureRenderMixin
. You can use it in some components to prevent unnecessary re-renders when the props and state are shallowly equal to the previous props and state: 
const PureRenderMixin = require('react-addons-pure-render-mixin')

const Button = React.createClass({
  mixins: [PureRenderMixin],
  // ...
})
