Use of parse in react

Parse+React mimics this flow by hooking into your component’s lifecycle. You first set up queries you want to associate with your component. Parse+React then subscribes your component to receive the query results, fetches the data in the background, passes it back to your component and triggers the component’s render cycle like so:

Data Fetch Lifecycle

Co-locating the Parse query in your component with the view makes it much easier to understand your code. You can look at your component code and see exactly how the queries tie into the view.
