 At first, this component might look okay. State is initialized to the value specified by props and updated when we type into the `<input>`. But if our component's parent rerenders, anything we've typed into the `<input>` will be lost! ([See this demo for an example.](https://codesandbox.io/s/m3w9zn1z8x)) This holds true even if we were to compare `nextProps.email !== this.state.email` before resetting.
 
-In this simple example, adding `shouldComponentUpdate` to rerender only when the email prop has changed could fix this. However in practice, components usually accept multiple props; another prop changing would still cause a rerender and improper reset. Function and object props are also often created inline, making it sometimes hard to implement a `shouldComponentUpdate` that reliably returns true only when a material change has happened. [Here is a demo that shows that happening.](https://codesandbox.io/s/jl0w6r9w59) As a result, `shouldComponentUpdate` is best used as a performance optimization, not to ensure correctness of derived state.

 Hopefully it's clear by now why **it is a bad idea to unconditionally copy props to state**. Before reviewing possible solutions, let's look at a related problematic pattern: what if we were to only update the state when the email prop changes?
