Why is useEffect running twice? This is due to StrictMode most likely in your root tree.

🤔 What is strict mode?

StrictMode is a tool for highlighting potential problems in an application.

How does it make useEffect() run twice?

It activates additional checks and warnings for its descendants, or in other words... renders twice.

Note: Strict mode checks are run in development mode only; they do not impact the production build.
