Don’t copy-paste code. Type it out. ?

Copy-pasting code without understanding leads to Cargo Cult programming, increasing risks of bugs and unintended side-effects. Typing code manually, rather than copying, improves learning by engaging direct practice over passive reading. This method helps developers understand language features, libraries, and naming conventions, reducing errors like forgotten attribute changes. Using techniques like TDD can prevent false positives in tests. The key is to learn from others' code by typing and understanding it, not blindly copying.
