I was doing a code review for a colleague when I found it.
The component had five useEffect hooks.
No errors. No warnings in the console. The PM had signed off on it. It had been in production for three months.

A few months ago, I found myself doing something I hadn’t done before.

Not because it was complex.
But because it felt hostile.
You know that feeling: the file keeps scrolling, props are flying around, and every small change feels like it might break so...
