String literal union type vs enums

// With string enums
export enum ButtonStatus {
  HIDDEN = 'HIDDEN',
  ENABLED = 'ENABLED',
  DISABLED = 'DISABLED',
};

// With union types of string literals
type ButtonStatus = 'HIDDEN' | 'ENABLED' | 'DISABLED';

As a general rule, string literal unions are a better default.

String literal unions

• Work without any need to import
• Simple to extend
• Switch statements require all paths for a union (better maintenance)
• Removed at compilation

Enums

• Can be iterated over
• Easier to rename/refactor?
