TypeScript strict mode is a foundational configuration setting that significantly elevates the robustness and maintainability of JavaScript projects by enforcing a comprehensive suite of rigorous type-checking rules. Activated through the "strict": true flag in the tsconfig.json file, this mode consolidates several individual strictness flags, compelling developers to write more explicit, safer, and less error-prone code. Its primary purpose is to catch potential type-related issues during development rather than at runtime, thereby reducing bugs and improving the overall stability of applications.
