JavaScript Closure for Creating a Counter

// Function to create a counter using closure
function createCounter() {
    let count = 0;

    // Closure: Inner function maintains access to the outer function's variable
    return function() {
        count++;
        return count;
    };
}

// Create a counter using the createCounter function
const counter = createCounter();

// Usage: Increment and display the counter value
console.log(counter()); // Output: 1
console.log(counter()); // Output: 2
