filehandle.readLines() Method

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

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

From the example next to this theory — filehandle.

Trap — only saying “filehandle.readLines Method” with no example. Fix that before you talk about advanced Node.js.

Viva: what is filehandle.readLines() Method? Then show the smallest filehandle.readLines Method example you can type. Then name the trap.

Exam tip

What is filehandle.readLines() Method? Show this: the smallest filehandle.readLines Method example you can type. Trap: only saying “filehandle.readLines Method” with no example.

Example

// filehandle.readLines() Method
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));

filehandle.readLines() Method: find user 2, then list names. Say both prints.
