[SOLVED] Sum All Primes fails at 977

Tell us what’s happening:
Can anyone tell me why this code fails when number 977 is tried? It works with 10 and 17.

Thanks in advance!
Your code so far

function isPrime(num) {
  var count = 0;
  for(var i = 1; i <= num; i++)
    if(num % i === 0) count++;
  if(count === 2) return true;
  return false;

function sumPrimes(num) {
  if(num <= 1) return 0;
  var sum = 0;
  for(var curr = 2; curr <= num; curr++)
    if(isPrime(curr)) sum += curr;
  return sum;

There doesn’t seem to be a problem. Your code passes when I tried it.

lol :smiley:

Glad it passes somewhere. I guess it might be the memory problem? Read some comment about that on Youtube video about this challenge.

Do you get any sort of error in the browser console?

You mean error in console related to the whole website or?
I do get 2 dead object errors from freecodecamp website.

EDIT: Interesting thing. I tried the same code on my sisters 2015 MacBook Pro on Chrome browser and it works.

I was going to ask you to try on another browser on your computer :smiley:

Or try hitting the reset button first.

Tried it on MY laptop on Google Chrome. Works again.
So, it’s the problem with Firefox. I’ll try restarting it.
I thought my code doesn’t work for some reason (I didn’t know the reason) and i said some really bad words while trying to solve this. :smiley:

Thank you again for help!
