You want to use an enum OrderStatus in Angular to represent these states: Pending, Shipped, Delivered, and Cancelled. You also want to display user-friendly text for each status in your template. Which approach is best?

AUse only strings in enum and display enum keys directly

BDefine enum with numeric values and create a mapping object for display text

CUse separate string constants instead of enum

DUse enum with mixed string and numeric values without mapping

Step-by-Step Solution

Solution:

Step 1: Understand enum usage for fixed states
Using numeric enums keeps code efficient and clear for logic.
Step 2: Provide user-friendly text separately
Mapping numeric enum values to display strings allows flexible, readable UI text.
Step 3: Evaluate other options
Using only strings or constants reduces type safety or clarity; mixed enums without mapping cause errors.
Final Answer:
Define enum with numeric values and create a mapping object for display text -> Option B
Quick Check:
Numeric enum + mapping = best practice [OK]

Quick Trick: Use numeric enums plus a display map for UI text [OK]

Common Mistakes:

Using mixed enum types without mapping
Displaying enum keys directly without user-friendly text
Avoiding enums and using loose string constants
