Sum of All Primes

Sum of all primes numbers
THANK YOU SO MUCH!!!! I thought that i is increased with every iteration and that’s why I thought i = 3, because when x = 4, was the second iteration and that it would be i = 3. but now I still don't understand, if x = 5, the i is still 2? beacouse if i is still 2, the condition of (i === x -...- CrxC01

Sum of all primes numbers
Thank you for your answear. but I don't understand the part where: x++; x=4; i=3; I don't know how my the code does not add 4 beause the condition of ``else if `` is applied: (i===x-1); (3 === 4 -1 ) added(which is 5 ) += 4 (is reciving 4 becouse is executing this line of code else if...- CrxC01
