Watch how people fix stuff in real life, like mechanics or carpenters. They learn by messing up so many times their hands just know what not to do. Coding feels the same way after a while.
Absolutely see that with coding too, where your fingers just start fixing syntax errors before your brain even processes them. It's all that repetition building a kind of muscle memory for problem patterns. You stop thinking about each semicolon and start feeling the shape of a working function. That deep knowing only comes from breaking things and patiently putting them back together, over and over.
Actually @brian_martin75, it's less about the hands knowing what not to do and more about them recognizing the pattern for what works. The muscle memory gets talked about a lot, but it's really your brain getting faster at spotting the right shape for the solution, not just avoiding past errors.
