This book flips the script of generic programming manuals, using humor to teach by bad example. Discover how to become the world’s worst programmer and build bad habits that lead to buggy, poorly written code. Do you dream of writing code that gets instantly rejected in review? Do you look forward to reading feedback plastered in comments like "WTF???" Do you hope your bug-ridden changes sneak through and wreak havoc in the codebase? If your goal is to build a reputation for writing creaky, messy, error-prone code that drives your teammates up the wall, Bad Programming Practices 101 is here to help. Alternatively, you could use this book to identify those bad habits and learn to avoid them. It covers topics like the foundations of programming (layout, variables, loops, and modules) and is revised with a NEW chapter on how NOT to use AI for writing code. It’s been said that you need to write 10,000 lines of bad code before becoming a good programmer. This book helps you to fill that quota while truly understanding the “why” behind best practices. What You Will Learn: Become a better coder by learning how (not) to programChoose your tools wiselyThink of programming as problem solvingDiscover the consequences of a program’s appearance and overall structureExplain poor use of variables in programsAvoid bad habits and common mistakes when using conditionals and loopsSee how poor error-handling makes for unstable programsSidestep bad practices related specifically to object-oriented programmingMitigate the effects of ineffectual and inadequate bug location and testingLearn how to avoid sabotaging your code with misuse of AI tools Who This Book Is for: Those who have some practical programming knowledge (can program in at least one programming language), but little or no professional experience, which they would like to quickly build up. They are either still undergoing training in software development or are at the beginning of their programming career. They have at most 1-2 years of professional experience.
