Brayan Arrieta Alfaro It's my pleasure and if you like you can edit the blog and provide people with codesandbox URLs for the above hooks as working examples you can either fork the codes to your workspace on codesnadbox or just use them from my workspace! useTimeout Hook example https://codesandbox.io/s/settimeout-example-timer-qtnih?file=/src/App.js usePrevious Hook example https://codesandbox.io/s/useprevious-example-luyyj useInterval Hook example https://codesandbox.io/s/useinterval-hook-timer-s3qb2 useFetch Hook example https://codesandbox.io/s/usefetch-hook-json-data-from-a-url-dymp4

Brayan Arrieta Alfaro Thank you for this very helpful Hooks example usage but I want to point out that there is a little warning that I got with this line of code at the useFetch Hook section, So if you take a look, it seems the useEffect hook depends also on the error value besides the url and options!
