Production strict mode requires enabling strict, noImplicitAny, strictNullChecks, noUnusedLocals, noUnusedParameters, and exactOptionalPropertyTypes to enforce type safety and eliminate implicit any errors.

Use TypeScript interfaces for defining object shapes and type aliases for unions or intersections to ensure clear type usage patterns, improve readability, and avoid any throughout your codebase.

Common TypeScript anti-patterns include using any types, inconsistent import and export conventions, improper async error handling, and neglecting utility types like Partial, Pick, Omit, and Record.

Handle async patterns safely by using explicit return types, avoiding any, and implementing robust error classes to catch and manage runtime exceptions effectively in your TypeScript code.

Use TypeScript utility types like Partial, Required, Pick, Omit, Record, Readonly, NonNullable, ReturnType, and Parameters to transform existing types safely without duplicating type definitions.

Yes, these TypeScript best practices apply across frontend, backend, and library projects, guiding compiler configurations, type definitions, and consistent pattern choices for production-ready code.
