What is the best way to pass dynamic data to a react component?

Question

JavaScript

I'm working on a chart component and I need the data to be displayed reactively. What is the best way to pass them to the component? props are used for immutable data. What if you need to update the chart every 3 seconds?

Answer 1

via props. Decompose the component if it is large so that the diagrams are as independent as possible. Also, read about reconcillation (key, index, shouldComponentUpdate).
React is smart and understands which part of the tree to update based on virtual DOM diffs.
