Be careful when using React.useEffect() hook because it can generate infinite loops.

useEffect() React hook manages the side-effects like fetching over the network, manipulating DOM directly, starting and ending timers.

While the useEffect() is, alongside with useState() (the one that manages state), is one of the most used hooks, it requires some time to familiarize and use correctly.

A pitfall you might experience when working with useEffect() is the infinite loop of component renderings. In this post, I’ll describe the common scenarios that generate infinite loops and how to avoid them.

If you aren’t familiar with useEffect(), I recommend reading my post A Simple Explanation of React.useEffect() before continuing. Having good fundamental knowledge of a non-trivial subject helps bypass the rookie mistakes.
