TypeScript Enums: Use Cases and Alternatives

This blog post takes a closer look at TypeScript enums: How do they work? What are their use cases? What are the alternatives if we don’t want to use them? The post concludes with recommendations for when to use which approach. It covers enum basics, use cases (e.g., namespace for constants with primitive values, custom type with unique values, namespace for constants with object values), alternatives (e.g., object literals, union of string literal types), and how to perform exhaustiveness checks and enumerate members.
