I’d like to think that one of the things that most good developers continually strive for is writing the cleanest, most maintainable code possible.
Personally, I don’t know if there is an actual point at which you reach it – it’s the whole journey-not-a-destination thing – but that doesn’t mean that we shouldn’t continually aim to get better at what we do. In our case, that’s writing clean WordPress code.
The thing is, there’s only so far you can get on your own. You can read a number of books, follow the advice of some high profile programmers, and read as much of the “academic” material that you can get your hands on – and I think all of the above is great – but, at the same time, it only goes so far.
To that end, I think it’s worth seeking out other people in your same field to help provide some level of mentorship on how it relates to writing clean code because here’s the thing:
As much material as we can read written by other people, nothing beats interacting with those who are writing code in the same language(s) for the same APIs under the same coding standards and who are farther along than you in experience.
