How to solve: Create a Private State Counter using Closures?

Question

Accepted Answer

Closures allow inner functions to access variables defined in outer scopes:
1. Define `let count = 0` inside `createCounterInstance()`.
2. Return an object with two methods. Since these methods are declared inside `createCounter()`, they retain access to `count` even after `createCounter()` finishes execution.
3. Because `count` is not exposed on the returned object, it is completely secure and private.
