sourceMap.findOrigin(lineNumber, columnNumber) function in Node.js

sourceMap.findOrigin(lineNumber, columnNumber) function (nod) is a Node.js topic. In plain words you use it for a short sourceMap.findOriginlineNumber, columnNumber function nod example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest sourceMap.findOriginlineNumber, columnNumber function nod example you can type. Type it, run it, and say what you see. If you can do that from memory, you know sourceMap.findOrigin(lineNumber, columnNumber) function (nod).

From the example next to this theory — sourceMap.

Trap: only saying “sourceMap.findOriginlineNumber, columnNumber function nod” with no example. Fix that before you talk about advanced Node.js.

Viva: what is sourceMap.findOrigin(lineNumber, columnNumber) function (nod)? Then show the smallest sourceMap.findOriginlineNumber, columnNumber function nod example you can type. Then name the trap.

Exam tip

What is sourceMap.findOrigin(lineNumber, columnNumber) function (nod)? Show this: the smallest sourceMap.findOriginlineNumber, columnNumber function nod example you can type. Trap: only saying “sourceMap.findOriginlineNumber, columnNumber function nod” with no example.

Example

// sourceMap.findOrigin(lineNumber, columnNumber) function 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));

sourceMap.findOrigin(lineNumber, columnNumber) function in Node.js: find user 2, then list names. Say both prints.
