当没有什么东西应该那么大时，使用 nodejs 处理内存不足错误

Question

The exact error says "FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory" The program should get the prime number in the nth position but fails no matter how small the number is. What exactly does this error mean and how do I fix it?

var primes = [2, 3, 5];
var x = 0;
var y = 0;
var z = 6;
var nthPrime = function(number){
    while (primes.length <= number){
        y = 0;
        while (y <= primes.length){
            x = primes[y];
            if (z % x === 0){
                y++;
            } else{
                primes.push(z);
                z++;
            }
        }
    }
    console.log(primes[number]);
};
nthPrime(3);

Answer 1

The second while loop is an infinite loop. The else statement is happening more frequently than the if statement, after the first two iterations. This means the primes array is increasing in length faster than the y value. Work out the logic some more and this particular error should work itself out.
