After 1 year of working as android dev and coding in java, finally switched to another startup where everything is in Kotlin where I will be the only one maintaining that project.

Me: This code has almost no comments
Senior dev: Code is pretty self explanatory

FML

At least she spent 4 days with me and walked me through the code, so I'm not totally lost which is great!

I hate it when people say that only the code is sufficient. Well, guess why whoever is reading it came to you to ask questions about it, because obviously, it is not. How hard is it to include small comments which explain what you are doing or trying to do? It is not that hard, and you will thank yourself later if you have to look at your code after a long period of time.

Also, not everyone has the same background knowledge and experience, and not everyone knows the 10+ libraries you are using and what their specific functions do.

Yes, it can be all looked up but it takes forever. Just write a fking line explaining what you are doing.

It. is. not. hard.

And many newbies will thank you later.

(this could be a rant of it's own. lol. Sorry. Sensitive topic. I work a lot with 0 documented stuff where everything changes constantly and it is very frustrating sometimes)

Well, you are still lucky. Its been more than a month , i have developed 5-6 new features fir this company and yet i don't know how their 100 classfiles long mvvm app works ;/ . Its equally important to have code base explained
