100%. I worked alone for a few years. Again self taught web development. I tried to read the “best practices” for the languages I was learning. But it was bugs galore and code I feared maintaining after release.
I then spent 5 months at a company in a team where every bit of code went through a peer review process. Even I was responsible for reviewing others code. I learnt a hell of a lot, we barely had any bugs and if we found a bug, it was usually easy to fix. Since then, writing maintainable and (importantly) readable code is my standard and I try and help other Devs do the same.
