--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);
