    This is not a well written problem. This is bad.

    Hacky solution for the lulz:

    def has_cycle(head):
    c = 0
    while head:
        head = head.next
        c += 1
        if c > 1000:
            return 1
    return 0

     if head is None:
        return False
    
    slow = fast = head
    
    while fast is not None and fast.next is not None:
        slow = slow.next
        fast = fast.next.next
        
        if slow == fast:
            return True
    return False

    The challenge is broken in JavaScript. The temp var. in the main function should be let instead of const, so it can be reassigned.
