What are the dependencies in useEffect?
An example of an AI chatbot conversation about useEffect dependencies in React.
Can you explain what dependencies in useEffect are?
Sure! In React, dependencies in useEffect are values that the effect depends on. If any of these values change, the effect will re-run.
How do I know which dependencies to include?
You should include any state or props that your effect uses. This ensures that the effect runs whenever those values change.
What happens if I don't include a dependency?
If you omit a dependency, your effect might not reflect the latest state or props, leading to stale data.
Can I use an empty array as a dependency?
Yes, using an empty array means the effect will only run once when the component mounts, similar to componentDidMount.
