Love this idea! Might it be better to store the original title before changing it, and then restore the original title in the effect cleanup?

 

Shouldn't title be in the useEffect dependency array so that it reruns the effect if title changes?

I agree with @worsnupd that you should probably restore the original title in the cleanup.

 

Agreed! I totally missed that. The effect should list title as a dependency.

 

Can you explain whats going on here, specifically why the anonymous function is returned?

 

When you use this hook in a component, you want to set the title for the current component, You don’t have to set title for all of your components. So This anonymous function is fired when the componentWillUnmount() to set default title to the components that you don’t want to set a title to it.
