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

Don’t start sourceMap.findOrigin(lineNumber, columnNumber) function (nod) with jargon. Start with sourceMap.findOriginlineNumber, columnNumber function nod on Farhan's board. That is the whole point.

sourceMap.findOrigin(lineNumber, columnNumber) function (nod) order: meaning → one sourceMap.findOriginlineNumber, columnNumber function nod step Farhan can write from memory → one limit. Dumping ten features helps nobody.

Skip sourceMap.findOrigin(lineNumber, columnNumber) function (nod) and skipping the failure case for sourceMap.findOriginlineNumber, columnNumber function nod shows up in a campus project.

Farhan ships sourceMap.findOrigin(lineNumber, columnNumber) function (nod) in a campus project. That is the use case worth saying.

Don’t do this with sourceMap.findOrigin(lineNumber, columnNumber) function (nod): skipping the failure case for sourceMap.findOriginlineNumber, columnNumber function nod. Interviewers spot it in ten seconds.

sourceMap.findOrigin(lineNumber, columnNumber) function (nod) is not a lonely heading. Farhan ties it to sourceMap.findOriginlineNumber, columnNumber function nod on Farhan's board.

One breath for sourceMap.findOrigin(lineNumber, columnNumber) function (nod), then sourceMap.findOriginlineNumber, columnNumber function nod on Farhan's board, then skipping the failure case for sourceMap.findOriginlineNumber, columnNumber function nod. Sit down.

Exam tip

For sourceMap.findOrigin(lineNumber, columnNumber) function (nod): definition + a campus project + one failure.

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.
