Starter Code App State Reducers Codesandbox Explore this online starter code app state reducers sandbox and experiment with it yourself using our interactive online playground. you can use it as a template to jumpstart your development with this pre built solution. In part 2: redux concepts and data flow, we looked at how redux can help us build maintainable apps by giving us a single central place to put global app state. we also talked about core redux concepts like dispatching action objects and using reducer functions that return new state values.

This example demonstrates rendering a deeply nested tree view and representing its state in a normalized form so it is easy to update from reducers. good rendering performance is achieved by the container components granularly subscribing only to the tree nodes that they render.

A redux reducer is a function that accepts an accumulation, new values, and returns a new accumulation. you can have multiple reducers. Extracting state logic into a reducer components with many state updates spread across many event handlers can get overwhelming. for these cases, you can consolidate all the state update logic outside your component in a single function, called a reducer.
