The Importance of Clean Code
summary
The talk argues for concrete practices to keep JavaScript/TypeScript code clean: write very small functions (≤2 indent levels), minimize arguments by extracting objects, follow single-responsibility and avoid side effects, and use fast tests with a red-green-refactor cycle for CI. It also recommends removing unhelpful comments in favor of descriptive names, apply the Boy Scout rule to always leave code cleaner, and consider TypeScript interfaces and automated checks to make refactoring and onboarding easier.
