Everyone who self taught themselves code, how did you do so? Books, websites, any recommendations?

Ok, so I need some clarity from you good folk, please.

My lead developer is also my main mentor, as I am still very much a junior. He carved out most of his career in PHP, but due to his curious/hands-on personality, he has become proficient with Golang, Docker, Javascript, HTML/CSS.

We have had a number of chats about what I am best focusing on, both personally and related to work, and he makes quite a compelling case for the "learn as many things as possible; this is what makes you truly valuable" school of thought. Trouble is, this is in direct contrast to what I was taught by my previously esteemed mentor, Gordon Zhu from watchandcode.com. "Watch and Code is about the core skills that all great developers possess. These skills are incredibly important but sound boring and forgettable. They’re things like reading code, consistency and style, debugging, refactoring, and test-driven development. If I could distill Watch and Code to one skill, it would be the ability to take any codebase and rip it apart. And the most important component of that ability is being able to read code."

As you can see, Gordon always emphasised language neutrality, mastering the fundamentals, and going deep rather than wide. He has a ruthlessly high barrier of entry for learning new skills, which is basically "learn something when you have no other option but to learn it".

His approach served me well for my deep dive into Javascript, my first language. It is still the one I know the best and enjoy using the most, despite having written programs in PHP, Ruby, Golang and C# since then. I have picked up quite a lot about different build pipelines, development environments and general web development as a result of exposure to these other things, so it isn't a waste of time.

But I am starting to go a bit mad. I focus almost exclusively on quite data intensive UI development with Vue.js in my day job, although there is an expectation I will help with porting an app to .NET Core 3 in a few months. .NET is rather huge from what I have seen so far, and I am seriously craving a sense of focus. My intuition says I am happiest on the front end, and that focusing on becoming a skilled Javascript engineer is where I will get the biggest returns in mastery, pay and also LIFE BALANCE/WELLBEING...

Any thoughts, people? I would be interested to hear peoples experiences regarding depth vs breadth when it comes to the real world.

I was always into computers, ever since I was a kid. Played a lot of videogames on Windows 98 and XP, and a lot of my earliest drawings were level ideas for those games. My first encounters with code were with game creation software like GameMaker, but I barely touched the code proper outside of editing a few variables from other people's code. After that I basically forgot all about it and spent most of my teen years being a shutin.

Skip ahead to my last year of high school without much idea on what to do. I was good at math when I wasn't being a lazy shit, so between that and what my parents expected of me, I was prepared to go to university for civil engineering. However, two things changed that decision, the first being a great IT professor, when me and a friend were so far ahead, he started assigning us some harder work, and suggested we study computer science at university. The second was a super jank and obscure open-source early 2000's game that somehow still has a thriving community and is actively being developed. I stumbled upon it by chance, and after playing for a while, I submitted a balance change on the GitHub repo. Even though it was just a single variable change, that time I got it. That time I saw how powerful programming could be and what could be done with it. I submitted PR after PR of new features, changes and bugfixes, by the time I left there I had a somewhat solid grasp of the fundamentals of programming, and decided to enrol in the computer science degree.

Enrolling was possibly the best decision I ever made (not america; debt isn't an issue), as well as giving me actual social skills, every course I took just clicked. The knowledge I already somewhat intuitively had a vague grasp on from videogames, general computer use and collaborating with russian coders who produced the jankiest shit that was still somehow functional was expanded upon and consolidated with a high-quality formal education. Four years later and I'm fresh out of uni, it was a long road between when the seed was first planted in my mind and now, but I've finally found out what I want to do with my life.

won't know for sure until i find a job though ffs

I'm late to programming, took me some years of working for dumbasses in the building industry to realise that i was meant for it.

When I left high school I thought that technology would never be a career on my old and undeveloped hometown (still isn't but i never contemplated the fact of moving to other county back there)

Glad to finally realise it :) being able to be proud of your work and to build something meaningful is great.

Also, to be able to work from home and hang out with my dogs is the best :)
