Companies spend $85 billion annually fixing bad code, largely due to developers lacking fundamental software design principles. JavaScript's low barrier to entry and bootcamp culture have produced many developers who can write working code but lack knowledge of SOLID principles, testable code design, and maintainability practices. The author argues that Agile development requires clean, flexible, testable code — and that the industry needs to prioritize teaching software design principles alongside syntax and frameworks. TDD is presented as a valuable but misunderstood practice, and SOLID principles are highlighted as a path toward writing maintainable, testable JavaScript and Node.js code.
