I’ve been into PHP programming for 10 years now. I decided to start learning NodeJS for a side project that I am rewriting and got from https://github.com/sergtitov/NodeJS-Learning to this interesting comparison between PHP and NodeJS from https://webapplog.com/php-vs-node-js/
Another comparison I have found is from SitePoint https://www.sitepoint.com/sitepoint-smackdown-php-vs-node-js/
The GitHub repo above has a lot of interesting tutorials and starting points, a bit outdated but still good.
Also, might worth watching this series on YouTube https://www.youtube.com/playlist?list=PLw5h0DiJ-9PAfwX0dGsQqCXXbTwQyXP8E
