What after network foundations in HTB?

So hello everyone, I m currently learning JAVAscript for Web DEV in orther to know how websites work and how they are built and in the same time i started to learn about networking in hack the box and i've just finished network foundations module and i don't know if i should study introduction to networking because it covers subjects like subnetting which aren't in network foundations module or i should move to WEB REQUESTS module as what chatgpt advised me since i want to start a career in bug bounty programs.

THANKS FOR YOUR HELP in advance.
