3 Ways to Fine-tune Presentational Components

Three ways to fine-tune your React presentational components  #reactjs #javascript

  • Here are three ways I’ve found to make React presentational components work as re-usable building blocks.
  • Here are two stories for a text input component: the first shows the component in its valid state, and the second show the component in its invalid state.
  • Instead, extract a new component and pull it up: – – Let the container decide explicitly when and where show presentational components.
