Here's a breakdown of what the code does:\n\n1. It exports a function called `fizzbuzz()`.\n2. Inside the function, an empty array called `fizzbuzz` is initialized.\n3. The function uses a for loop to iterate from 1 to 100.\n4. For each number, it applies the FizzBuzz rules:\n   - If the number is divisible by both 3 and 5 (i.e., divisible by 15), it adds 'FizzBuzz' to the array.\n   - If the number is only divisible by 3, it adds 'Fizz' to the array.\n   - If the number is only divisible by 5, it adds 'Buzz' to the array.\n   - For any other number, it adds the number itself (as a string) to the array.\n5. Finally, the function returns the completed `fizzbuzz` array.\n\nThis implementation is concise and follows the standard FizzBuzz rules. It's a good example of how to solve this common programming challenge in TypeScript. Would you like me to explain any specific part of the code in more detail or suggest any improvements?","stopReason":"end_turn"}
