pureRender(shouldComponentUpdate = notShallowEqual)(Component)

Wraps Component in a function comparing prevProps & props. If shouldComponentUpdate returns false, the last value returned by Component(similarProps) is returned.

By default, if prevProps and props have a shallow equality, the value is left untouched. You can use a custom function to compare them:

const customShouldComponentUpdate = (prevProps, props) =>
  prevProps._id !== props._id

pureRender(customShouldComponentUpdate)(MyComponent)
