I have listed enough resources to learn no-stack to full-stack.

Please add here if you guys found any useful resources.

https://www.freecodecamp.org/learn

They accomplish this by creating thousands of videos, articles, and interactive coding lessons - all freely available to the public. They have included machine learning courses, interview preparations, frontend, backend, and more...

https://www.codecademy.com/catalog/all

Codecademy provides free and paid courses which I found really useful for getting started.

https://www.sololearn.com/Courses/

Some of us may be heard this site, I used to learn basics from their mobile application years back. They have covered all programming languages and quizzes each.

https://javascript30.com/

This covers javascript fundamentals after their beginner level. Personally I found this to get to know more about vanilla javascript, which is really more important.

https://scrimba.com/allcourses

The most favorite way of learning I experienced is scrimba courses. They provide advanced interactive learning while watching the course, play with mentors code on go. They cover mostly everything on the frontend.
Definitely check it out.
