Writing clean code is essential for building scalable software and maintaining velocity over time. Clean code practices—meaningful naming, single responsibility, testing, and proper documentation—reduce technical debt that becomes exponentially more expensive to fix later. A 2022 industry report estimated poor software quality cost the U.S. $2.41 trillion, with technical debt accounting for $1.52 trillion.
