Help Learning JavaScript!

Hey everyone! Earlier I decided to learn front-end development to work on projects to put on my resume. I’ve watched tutorials online and I’m fairly comfortable with html and css. But when I try to look for JS tutorials, I get the very, and I mean, VERY basic JS. I see 40 minute videos on how to declare variables l, how to loop, etc. I already know languages such as python, Java, golang, pretty much back-end languages, so my question is, how can I learn JS without going over the basics? How can I learn JS in relation to building pages, in order to familiarize myself enough and move on to node.js, react.js, etc. any help/any pointers would be highly appreciated!

Thanks!
