Replace any with precise types or unknown when the type is truly undefined, and use type guards to safely narrow values down during runtime checks.

Use unknown instead of any when the value type is genuinely uncertain, enforcing explicit type narrowing through type guards before any property access.

Configure strict linting rules and tsconfig compiler options to catch unsafe patterns early, prevent explicit any usage, and enforce explicit type annotations across the project.

Leverage generics and utility types to model reusable, type-safe APIs that enforce strict type checking, prevent unsafe casting, and improve overall code maintainability.

Strict TypeScript practices apply universally across frameworks, enforcing explicit types, preventing any usage, and implementing type guards to ensure consistent type safety everywhere.

TypeScript allows unsafe operations when strict mode is disabled; enabling strict tsconfig options and ESLint rules eliminates any usage and enforces explicit type guards.
