        // Example of a simple iterator in JavaScript
        function* numberGenerator() {
            let index = 0;
            while (index < 5) {
                yield index++;
            }
        }

        const numbers = numberGenerator();
        for (const number of numbers) {
            console.log(number); // Outputs: 0, 1, 2, 3, 4
        }
