TASK: Sum all the prime numbers up to and including the provided number.
function sumPrimes(num) {
var total = 0;
// check if n is prime by dividing n for all numbers up to n-1
function isPrime(x) {
if (x<2) {return false;}
for (y=2; y<x; y++) {
if (x%y===0) {return false;}
}
return true;
}
//loop through numbers up to num
// if they pass the test, add them to the total
for (i=num;i>1;i--){
if (isPrime(i)){
total+=i;}
}
return total;
}
sumPrimes(10);
