Hi there, nice to meet you. I’m 14 and i’ve used codecademy to learn HTML, CSS, JavaScript and ReactJS. It was a really good experience for me, although i did not pay anything. The most interesting stuff are paid unfurtunatley.
If you want to make games then you may check Unity, wich uses C#, or Godot, wich uses GDScript (Similar to Python and lua)
Just use perfume
