How to become a better engineer?

Learn more in depth about how different parts of browser interact with each other, what’s the real logic behind state changes, how browser actually works, how does it handle web APIs, dom manipulation in depth
Once you are done with these things move towards architecture kind of things like what is micro-frontend architecture, how communication happens between Frontend server and database, how pipelines work

Slowly slowly start progressing with advanced topics and you will keep getting better and better

Thanks man. Makes sense
