60 passed, only missed one
Expected: '[949861, 698230]', instead got: 'null'

Anyone the same?
What could be the issue on my code?

1. Spoiler flag!!!
2. If this is JS, there's 537 completions already, and the tests are correct. If you're timing out, it's problem with your code, and not KATA itself. (I see you're checking every number to see if it's prime, there's a faster way...)
3. If you post code, format it properly (LINK)

now I see that more options appear...
added the null version and now I don't calculate all the prime numbers just the first 100 (enough to find the solution and much faster)
anyway, it says timeout...

I don't know, it says that it takes too much time when it solves everything.
What could I edit or change? (I still need to learn a lot I guess haha)
You can see my code right?

If it doesn't pass, nothing is solved:-) Not an issue of the kata since 533 people passed the JS kata. Something wrong in your code?

I mean, everything seems to be solved but it doesn't pass :(

Alright, thanks!

Brute force will not work. There is a mathematical solution that you can find with basic research. Good luck!
