Node.js is secure when used correctly, but like any technology, it can be vulnerable to security threats if not properly configured or maintained. Node.js has a built-in module called for handling secure encryption and decryption, and there are many third-party modules available for handling authentication, authorization, and other security concerns.
Node.js is not visible in the browser like JavaScript. Node.js is a server-side runtime environment that executes JavaScript code on the server, while JavaScript is a client-side programming language that runs in the browser. Node.js can interact with the browser through requests and responses, but it does not directly manipulate the or render to the client like JavaScript does.

What else can I help you with?
How can you close the iframe in calling page in php and javascript?
Using JavaScript, you can accomplish this by deleting the iframe node from the DOM.
What is a node id?
It is the value of the attribute id of a node. It is used when manipulating the DOM and can be accessed by using the function getElementById() of the document object in JavaScript
Can you hide and reveal text e.g YouTube comments without the use of javascript I wanted to try it on Myspace but it disables javascript.?
Very unlikely. See, Javascript is used to change the className attribute of the text node. When the className has changed, the node uses the properties that are set with CSS. This means you can keep a text invisible with CSS only, but you'll always need Javascript to switch classes.
What is node?
A node (knot) is a point along a standing wave where the wave has minimal amplitude. The opposite of a node is an antinode, a point where the amplitude of the standing wave is a maximum. These occur midway between the nodes
Which switch provides good deep packet inspection?
Use the SonicWALL Secure TZ 180 Wireless 25 Node switch.
Write an iterative function to search an element in a binary search tree?
_node* search (_node* head, _key key) { _node* node; for (node=head; node != NULL;;) { if (key == node->key) return node; else if (key < node.>key) node = node->left; else node = node->right; } return node; }
How to Print data of all nodes of linked list?
for (node=head; node!=null; node=node->next) printnode(node);
How to find the mirror image of a binary tree?
Refer to http://cslibrary.stanford.edu/110/BinaryTrees.html void mirror(struct node* node) { if (node==NULL) { return; } else { struct node* temp; // do the subtrees mirror(node->left); mirror(node->right); // swap the pointers in this node temp = node->left; node->left = node->right; node->right = temp; } }
Can we use doubly linked list as a circular linked list?
Yes. The tail node's next node is the head node, while the head node's previous node is the tail node.
Algoritm for deleting the last element from a list?
Given a list and a node to delete, use the following algorithm: // Are we deleting the head node? if (node == list.head) { // Yes -- assign its next node as the new head list.head = node.next } else // The node is not the head node { // Point to the head node prev = list.head // Traverse the list to locate the node that comes immediately before the one we want to delete while (prev.next != node) { prev = prev.next; } end while // Assign the node's next node to the previous node's next node prev.next = node.next; } end if // Before deleting the node, reset its next node node.next = null; // Now delete the node. delete node;
Is null node equal to leaf node?
No. A leaf node is a node that has no child nodes. A null node is a node pointer that points to the null address (address zero). Since a leaf node has no children, its child nodes are null nodes.
What is an intrathoracic node?
An intrathoracic node is a node within the chest cavity.
