--description--

Given a positive integer up to 1,000, return the sum of all the integers squared from 1 up to the number.

--hints--

sumOfSquares(5) should return 55.

assert.equal(sumOfSquares(5), 55);

sumOfSquares(10) should return 385.

assert.equal(sumOfSquares(10), 385);

sumOfSquares(25) should return 5525.

assert.equal(sumOfSquares(25), 5525);

sumOfSquares(500) should return 41791750.

assert.equal(sumOfSquares(500), 41791750);

sumOfSquares(1000) should return 333833500.

assert.equal(sumOfSquares(1000), 333833500);

--seed--

--seed-contents--

function sumOfSquares(n) {

  return n;
}

--solutions--

function sumOfSquares(n) {
  let total = 1;
  for(let i = 2; i <= n; i++) {
      total += i * i;
  }
  return total;
}
