Can you suggest a way to understand and develop the right habits? Or Any good method to improve code quality at personal and team level?
Would be really useful for my case.
I imagine you'll get comments here like "have good code hygiene" and "aim for good test coverage", which are not wrong. However, for me, what really stuck was learning directly from senior developers.
Anecdotally, having at least one senior developer on a team dramatically changes the long-term prospects of a project, even if they are not the ones actually leading the project. I would be curious to hear other's experiences, to see if that generalizes.
(with the caveat that not all senior devs had good habits)
Unfortunately being senior is not a good indicator of someone's ability to design and write good code. Yes, it should be. No, it not always is, as my experience shows.
Now, if you are senior yourself, probably, you can see that. But when you're junior developer it's very easily to misguide yourself by looking at the senior staff without questioning anything.
So, I'd add to your advice this. Yes, learn from senior developers by observing what they do and then read more about the topic to see if they are doing right thing. Also, try to find out what are the other approaches and opinions. Even if you don't agree with them it's good to diversify your knowledge.
Is the correct thing that doesn’t work correctly under some conditions always the correct thing. Users are polite and will not tell you about the annoying whack a mole bugs that keep cropping up...
For me Clean Code was a bit of an eye opener. I generally found following SOLID principles to be valuable.
It's however important to understand that principles are not unbreakable laws of the universe, but rather things that should guide you but that are also subject to questioning.
