re: React: useEffect explained with lifecycle methods VIEW POST


Small typo in the last code snippet. I believe you meant componentDidMount rather than componentWillMount in the first comment.

Also equivalent instead of eqivalent.


Good catch. Thank you, I've fixed it now.


In addition to my previous comment, it is incorrect to say the dependency array doesn't affect the cleanup fn returned by the callback.

It is equivalent to componentDidUnmount if an empty array is passed, otherwise it will run whenever a dep changes, after the component has rendered with new props.

Double checked with docs, you're right. I've fixed the post. Thank you again.
