Magento Code That Sucks
Bad Magento code is not random. It follows a few patterns.
You've opened a file before, a legacy project, a colleague's module, your own code from two years ago, thought some version of "this code sucks", and closed it again without a plan.
That's because messy Magento code usually isn't random. It's the same handful of mistakes repeating: god classes, hidden side effects, plugins fighting each other. Once you can name the pattern, the fix stops being a guess.
This course walks real, messy Magento code and refactors it live.
One anti-pattern at a time, from diagnosis to a working refactor you can compare line by line. Each lesson ends with the same file, cleaner than it started.
This is specialized topics, step 4, the last step of the specialized topics for now. Every new course ships into the University first, so what comes after this one arrives there.
You leave able to look at someone else's Magento code, including your own, and know exactly where to start.
