What is the dependency array in useEffect?
An example of an AI chatbot conversation about understanding the dependency array in useEffect.
What is the dependency array in useEffect?
The dependency array in useEffect is a second argument that lets you control when the effect runs.
Can you give me an example of how to use it?
Sure! If you pass an empty array, the effect runs only once after the initial render.
What happens if I include variables in the array?
Including variables means the effect will re-run whenever those variables change.
Is it possible to have multiple effects in one component?
Yes, you can have multiple useEffect hooks in a single component, each with its own dependency array.
