Private Counter Factory
CHALLENGE
Difficulty: intermediate+25 XP
Write a function makeCounter() that returns an object with two methods:
- increment() — adds 1 to a private count and returns the new value
- value() — returns the current count without changing it
The count must start at 0 and be completely inaccessible from outside — calling the factory twice must produce two independent counters.
