Tell us what’s happening:
this code works well for small value inputs but for the large values it is not working

Your code so far

function checkprime(i,numo)
  var count=0;
  for(var j=1;j<numo;j++)
    return 1;
  return 0;
function sumPrimes(num) {
  var sum=0;
  for(var i=1;i<=num;i++)
  return sum;

I can see what’s wrong. 977 is a prime, which is why your code doesn’t work. I suggest you try it on smaller primes such as 3, 5 and 7 and try to think about why it’s not working for those. If you need more hints feel free to ask again.
