Ejs in Node.js

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

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

From the example next to this theory — Ejs in Node.

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

Viva — what is Ejs (in node)? Then show the smallest Ejs in node example you can type. Then name the trap.

Exam tip

What is Ejs (in node)? Show this: the smallest Ejs in node example you can type. Trap: only saying “Ejs in node” with no example.

Example

// Ejs 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));

Ejs in Node.js: find user 2, then list names. Say both prints.
