Do you follow Just-in-Time Learning?
Do you follow Just-in-Time Learning?
I have about 2 YoE, and I'm sure this changes with more experience.
I often hear this idea online that programmers should follow "just-in-time" learning, meaning you should prefer to learn things you don't know while on the job. ( The way some people talk about it, though, it sounds like you shouldn't dare spend a single minute learning anything new outside of your 9-5. )
This seems generally reasonable advice, especially for simpler things that take a few hours like learning a specific language feature, library, or similar. But when I lean too much on this JIT learning, it feels possibly detrimental.
Many times I do something big and new to me, say, deciding how to approach auth, microservice architecture design, automated testing, containerization, etc., I end up making a big decision after a few hours or days of cursory reading on documentation and blogs, only to come to regret it some months later. At that point, maybe I'll slow down, find a book on the subject, read it, and think, "Oh, darn, I wish I knew that N months ago." It certainly feels like spending more time learning upfront could have avoided mistakes due to lack of knowledge. Though there's no way to go back in time and know for sure.
I'm not asking about any area listed in particular. I feel like, for all of those, I've learned more in the time since, and would probably avoid some of my prior mistakes if I did it again. The question is more: How much do you subscribe to this idea of just-in-time learning? And if you do, how do you know when you've learned enough to be confident, or when you need to slow down and learn in more depth?
You're viewing a single thread.
If you want to level up your game, find a new job, or grow into a new role, by all means take a course or training on your own time. All of the concerns that you listed are probably worth spending dedicated time to upskill on.
If you stay in this field for much longer, you're going to run into a lot of cases where the thing you've been doing is replaced with the New Thing. The New Thing will have a couple new ideas, but will also fundamentally handle the same concerns as your Old Thing, often in similar ways. Don't spend your free time chasing the New Thing without getting something out of it - getting paid, making a project that you wanted to make anyways, contributing to New Thing open source projects.
If you sink work into the New Thing without anyone willing to pay for it, that's fine, but it means that you might never get someone to pay for it. Most companies are more than willing to hire experienced Old Thing devs on New Thing jobs, and will give you some time to skill up.
