Back to Home#### squareSum

mathbeginnerSquares each number in an array and then sums the results together.

Use `Array.prototype.reduce()`

in combination with `Math.pow()`

to iterate over numbers and sum their squares into an accumulator.

const squareSum = (...args) => args.reduce((squareSum, number) => squareSum + Math.pow(number, 2), 0);
