Hi,
I have been generating prime numbers in JavaScript i want to return true
if it's a prime or false if it'not below is the code i am struggling with
it. If a number is not a prime it should return false but it's not.
function isPrime(number){
d = number-1;
while (d > 1){
if ((number % d) == 0) return false;
d--;
}
return true;
}
if (isPrime(19)){
alert('Prime');
}
else{
alert('Not Prime');
}
//return 'false';
var val = isPrime();
document.getElementById('output').innerHTML = val;
