New to Coding. What do i do next after Javascript & jQuery? [closed]

I am trying my best to lock in and give this journey all i have got but i am stuck. I need a map, I need a mentor.
A friend gave me a course on HTML, CSS and JavaScript but i have completed it. What next?

I just need a map to be honest. I want to be a Full Stack Developer. Don’t laugh at me, i know it is possible.
