Top-down data flow is just component composition passing data and data-handlers down the child tree, as needed. This is the purest way of communicating with components:

• Easily modeled as pure components
• Portable between applications
• Simple to test

Typical Top-down implementations are implemented using FLUX based on a single application state:

Note: actions are pushed down the tree and each node can trigger re-renders as necessary
