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

Please add here if you guys found any useful resources.

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...

codecademy.com/catalog/all

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

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.

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.

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.
