JavaScript
1

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;
}

sumPrimes(10);

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?

5

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!
