Use `Math.pow()` to calculate power of each number and add all numbers into acculmulator. Use `Math.pow()` to calculate power of each number and add all numbers into acculmulator.
```js ```js
const squareSum = (arr) => arr.reduce((squareSum, number) => const squareSum = (...arr) => arr.reduce((squareSum, number) => squareSum + Math.pow(number, 2), 0);
squareSum + Math.pow(number, 2), 0);
``` ```
```js ```js
squareSum([1, 2, 2]); // 9 squareSum(1, 2, 2); // 9
