PinataLearn - Break Through the Complexity

🎉 A Closure is Just a Function + Its Environment!

That's it! A closure remembers variables from its outer scope even after the outer function has finished executing.

function createCounter() {
    let count = 0;  // Captured variable
    
    return function() {
        count++;  // Still accessible!
        return count;
    };
}

const counter = createCounter();
console.log(counter()); // 1
console.log(counter()); // 2
                    

The "mirage" shattered! Closures aren't complex - they're just functions with a backpack of variables they carry around.
