title: When to use reducer in storing data in a Redux app
body: <p>I'm quite new with Reactjs so I would like to ask what are the scenario where you would store data in reducer. For example if you have a list of data in a store and would like retrieve an item from the lists. Will it be efficient to just a request a get API call to fetch the item? I don't know if my scenario is right but Would like to ask some real world scenario that has been use in your application.</p>
