type-safety

You replace magic strings with typed constants by creating a constants module that exports `as const` objects, then refactoring string comparisons to reference these strict values for safer matching and autocomplete.

The `as const` pattern in TypeScript defines objects with strictly narrowed literal string types, creating a single source of truth for modes and statuses to prevent drift and enforce exact value comparisons.

No, you do not need external dependencies to enforce type-safety for string comparisons. You only need TypeScript to apply `as const` patterns and export typed objects for safer comparisons and autocomplete.

The best way to prevent typos and runtime errors from string literals is replacing magic strings with `as const`-typed objects, defining modes and statuses centrally to ensure autocomplete and safer comparisons.

Yes, you can use `as const` typed objects to define editor modes across React components. This creates a single source of truth that ensures consistency and prevents drift across all component comparisons.
