React is primarily for taking some data, and creating a UI to display it, so it's important to understand it's relationship with data. The most important thing to remember about React and data is that data flow is unidirectional. Data flows from the top of the component tree to the bottom. It can't flow back up the component tree. React provides two mechanisms for dealing with data, props and state. We need to think about the stability of the data. Data that does not change over the lifetime of a component should be considered as props. Data that can change should be considered as state. State should be the single source of truth for changing data, and should be kept in the highest common component of those that need the data. So any component lower down the tree that depends on it should receive the data as props.
