React + Redux ? Selectors inbound

I don't like diluting quality content, so I will be brief and link to a great article on the benefits of adding selectors to a react/redux application and how to do so.

Selectors:

  • act as a single-source-of-truth when mapping to your mapStateToProps() (very useful if being referenced in many components)
  • handle the logic for determining what state data you want, making your components less complex
  • can increase performance by only performing computation if the state arguments it is passed have changed since last time

Note - Only worry about this if you are already proficient with React and Redux
