-Multiple `.filter()` or `.map()` calls iterate the array multiple times. Combine into one loop.

-**Incorrect (3 iterations):**

-```typescript
-const admins = users.filter((u) => u.isAdmin);
-const testers = users.filter((u) => u.isTester);
-const inactive = users.filter((u) => !u.isActive);
-```
-
-**Correct (1 iteration):**
-

-const testers: User[] = [];
-const inactive: User[] = [];
