[Proposal] Memo in another manner #100

Description

@aralroca

Problem

memo approach is enough understandable. However is not 100% elegant solution... Especially if you have more "wrappers" like connect, withRouter, or other HOC:

export default memo(
  connect(mapStateToProps, mapDispatchToProps)(MyComponent),
)

Proposal

I will propose to do it following components configurations as displayName, propTypes, defaultProps...

MyComponent.displayName = 'NameOfMyComponent';

Something like:

export default function MyComponent() {
/* ... */
}


MyComponent.memo  = true;

or

export default function MyComponent() {
/* ... */
}

MyComponent.memo  = (nextProps, prevProps) => { /* ... */ };
