Prime Numbers JavaScript

Question

Can someone please give me guidance on getting the primenumbers here? This is homework so I don\'t want the answer but some pointers would be greatly appreciated. It\'s real

Answer 1

You should return a bool value and new function can be:

function(n) {
    if(n === 1) { return false;}
    else if(n == 2) { return true;}
    else if(n == 3) { return true;}
    else { 
        for(i=Math.floor(Math.sqrt(n));i>=2;i--){
            //console.log(i);//maybe another var in here? 
                if(n%i ==0 || n%2 ==0 || n%3 == 0) {return false;} 
        } 
        }
    return true;
};

In the OP, the control if(n%i !==0 && n%2 !==0 && n%3 !== 0) {return n;} was problematic because even if only single i satisfies this condition, the function returns the number as prime.
