Exam tip

Say fs.extra.ensureDir() (function) in one breath, then createReadStream, then loading the whole file into RAM.

Example

const fs = require("fs");
const path = require("path");

const file = path.join(__dirname || ".", "demo.txt");
fs.writeFileSync(file, "hello node\n");
const text = fs.readFileSync(file, "utf8");
console.log(text.trim());
fs.unlinkSync(file);

fs.extra.ensureDir() — fs reads/writes files. Prefer promises/async APIs in real apps.
