How do you optimize TypeScript code for better type checking and performance?

Thank you for posing such a critical question, especially in today's fast-paced software development environment where efficiency and safety are paramount. During my tenure at leading tech companies, optimizing TypeScript code for both better type checking and performance has been a core focus of mine. I'll share some strategies that have been instrumental in my projects, which I believe can serve as a versatile framework for others in similar roles. First, to enhance type checking, leveraging TypeScript's strict mode options is a practice I've consistently applied and recommend. By enabling strict in the TypeScript configuration, we enforce constraints like strict null checks, which catch null and undefined errors early. This practice significantly reduces runtime errors and improves code quality...
