To enforce TypeScript strict mode, enable strict settings in tsconfig.json and refactor code to remove any usage, prefer unknown, and replace type assertions with proper type guards for safer code.

The best way to replace non-null assertions in TypeScript is by applying type narrowing, defensive checks, and proper type guards instead of using the exclamation mark to ensure safe type safety.

Refactoring to immutable TypeScript patterns involves applying readonly modifiers to data structures, preferring type over interface for data, and removing unsafe casts to achieve strict immutability.

Yes, strict TypeScript discipline suits large applications by applying dependency-injection-friendly patterns and eliminating unsafe types, which enhances overall code safety and testability.

You should prefer unknown over any in TypeScript strict mode when a variable's type is truly uncertain, forcing you to apply explicit type guards and narrowing before safely accessing properties.

Type assertions break TypeScript strict mode discipline because they bypass the compiler's type checking, introducing unsafe casts that can cause runtime errors instead of using proper type guards.
