UIs and APIs

React UI Kits

Function Components vs Class Components

Same end goal, different API.

  • Functional programming model
  • Input props → Output element
     
  • Auto diffing to initialize behaviour
     
  • Methods for effect synchronization
  • Co-located logic
  • Object-oriented model
  • Input props → Object to compute outputs
  • Manual diffing to initialize behaviour
  • Methods for lifecycle of component
  • Co-located methods
function MyFunctionComponent {}
class MyClassComponent extends React.Component {}
