FizzBuzz task: write a JavaScript function that takes an array of numbers and returns an array where numbers divisible by 3 are replaced with 'fizz', divisible by 5 — with 'buzz', and divisible by both 3 and 5 — with 'fizzBuzz'.

javascript function fizzBuzz(arr) { return arr.map(num => { if (num % 15 === 0) return 'fizzBuzz'; if (num % 3 === 0) return 'fizz'; if (num % 5 === 0) return 'buzz'; return num; }); }

// Example usage: console.log(fizzBuzz([1, 3, 5, 15, 16])); // Output: [1, 'fizz', 'buzz', 'fizzBuzz', 16]
