finding sum of prime numbers under 250

Question

var sum = 0

for (i = 0; i < 250; i++) {

    function checkIfPrime() {

        for (factor = 2; factor < i; factor++) {
            if (i % factor = 0) {
            


        

Answer 1

You can equally use this

let sum = 0;
let num = 250;


for (let i = 2; i < num; i++) {
  let isPrime = true;
  
  for (let j = 2; j < i; j++) {
    if (i % j === 0) {
      isPrime = false;
    }
  }
  
  if (isPrime) {
    sum += i;
  }
}

console.log(sum);
