After finishing HTML, CSS and Javascripet coures, how can I plan to start my first code? Any idea?

Answer 1

You should have been writing little codes all the time while you were learning the tutorials.

The important thing for you is that you stop pondering and start coding, whatever it is!

Start easy, slowly increase difficulty and complexity.

You can search this forum for 'project ideas', or you look into Sololearn's sections Code Code or Community Challenges.
