You are correct, useEffect can be dangerous if you don’t know exactly what you are doing. I would go so far as to say that most people use it incorrectly. This includes myself, I am not great at using React and end up using it in the wrong places, which according to a colleague, it should just be avoided if possible.
You have no idea how correct you are. I moved from a small town to a massive city and after a while I noticed there was a lot less overweight people and people were just generally in better shape.
Move somewhere where you don’t need a car and can walk and take public transit. Humans are not built to drive around everywhere and only walk in parking lots.
