TypeScript coding standards are enforced by mandating object destructuring for function parameters, prohibiting redundant JSDoc comments, and preferring type inference over explicit declarations to ensure code clarity and robustness.

Handling TypeScript function parameters via mandatory named object destructuring eliminates positional arguments and ensures code clarity, making the codebase easier to maintain and refactor.

Adopting const objects over TypeScript enums provides safer type management and aligns with strict coding conventions that favor standard JavaScript patterns and discriminated unions.

Validating data at TypeScript I/O boundaries is achieved by using Zod. This approach prevents risky type assertions and ensures type safety from external inputs by validating runtime data structures.

Use discriminated unions in TypeScript to manage state and errors safely. They are preferred over type assertions, ensuring the compiler narrows types accurately without non-null assertions.

TypeScript code fails type safety checks when type assertions bypass compiler validation. Discouraging type assertions and non-null assertions in favor of explicit types and Zod I/O validation restores strict type safety.
