RIP Net Neutrality. Let's hope it comes back with a vengeance.

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.
