--description--
Write a function to find the sum of squares of an array of integers.
--hints--
sumsq should be a function.
assert(typeof sumsq == 'function');
sumsq([1, 2, 3, 4, 5]) should return a number.
assert(typeof sumsq([1, 2, 3, 4, 5]) == 'number');
sumsq([1, 2, 3, 4, 5]) should return 55.
assert.equal(sumsq([1, 2, 3, 4, 5]), 55);
sumsq([25, 32, 12, 7, 20]) should return 2242.
assert.equal(sumsq([25, 32, 12, 7, 20]), 2242);
sumsq([38, 45, 35, 8, 13]) should return 4927.
assert.equal(sumsq([38, 45, 35, 8, 13]), 4927);
sumsq([43, 36, 20, 34, 24]) should return 5277.
assert.equal(sumsq([43, 36, 20, 34, 24]), 5277);
sumsq([12, 33, 26, 18, 1, 16, 3]) should return 2499.
assert.equal(sumsq([12, 33, 26, 18, 1, 16, 3]), 2499);
