What to do after the fundamentals?

Question

**WHAT COMES AFTER BASICS AND BEFORE PRACTICE?**

I have looked everywhere for knowledge of JavaScript and other related languages.
Foundation/Beginner information is everywhere, in SoloLearn/YouTube/Udemy/Other apps.

But same thing is being repeated again and again for me now, where do I learn the next level or intermediate/advanced knowledge?

NOTE: I tried to practice things after learning basics, and I found some new things that I didn't knew everytime

The MDN Javascript guide is a good place to learn more about Javascript -
