Answer 2

Hey there!

As I can see from your profile, you have completed the HTML and CSS course.

For further knowledge on those topics, you can visit w3schools.com.

It is a great website with a huge database of nearly everything you need.

Secondly, I would suggest that you slow down your horses 😅 and first do basics of the other courses you mentioned.

Ofcourse, if you aim to be a pro, or good, you need a lot mre than what is provided.

These courses are fundamentals of coding. That doesn't mean that they aren't good. It means they obviously aren't enough.

These are really good to get started on coding and have a firm grasp of the essentials.

So first complete the above mentioned courses.
