TypeScript Enum
التعداد في TypeScript (Enum)
Definition
A TypeScript feature that defines a named set of constant values, giving semantic meaning to fixed option sets.
ميزة TypeScript تُعرِّف مجموعة مسماة من القيم الثابتة، مما يمنح معنى دلاليًا لمجموعات الخيارات الثابتة.
Why It Matters
On 404Fault, status fields like 'published' | 'draft' | 'archived' are string union types rather than enums — they serialize cleanly to Firestore without transformation.
في 404Fault، حقول الحالة مثل 'published' | 'draft' | 'archived' هي أنواع اتحاد سلسلة بدلاً من تعدادات — تُسلسَل بشكل نظيف إلى Firestore دون تحويل.

Example Usage
“// Prefer union types: type ProjectStatus = 'draft' | 'published' | 'archived'; // Over enums: enum ProjectStatus { Draft, Published, Archived }”
“// أفضّل أنواع الاتحاد: type ProjectStatus = 'draft' | 'published' | 'archived'; // بدلاً من التعدادات”
