Cross Site Scripting in Node.js

Cross Site Scripting (node js) is a Node.js topic. In plain words you use it for a short Cross Site Scripting node js example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Cross Site Scripting node js example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Cross Site Scripting (node js).

From the example next to this theory — Cross Site Scripting in Node.

Trap — only saying “Cross Site Scripting node js” with no example. Fix that before you talk about advanced Node.js.

Viva: what is Cross Site Scripting (node js)? Then show the smallest Cross Site Scripting node js example you can type. Then name the trap.

Exam tip

What is Cross Site Scripting (node js)? Show this: the smallest Cross Site Scripting node js example you can type. Trap: only saying “Cross Site Scripting node js” with no example.

Example

// Cross Site Scripting in Node.js
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

Cross Site Scripting in Node.js: find user 2, then list names. Say both prints.
