Buffer.readInt32LE() Method

Buffer.readInt32LE() Method is a Node.js topic. In plain words you use it for read a big CSV in an upload job. Don’t start with a slogan — start with that picture.

Smallest example: createReadStream. Type it, run it, and say what you see. If you can do that from memory, you know Buffer.readInt32LE() Method.

From the example next to this theory: Buffer.readInt32LE() Method — buffer holds raw binary data outside the V8 string heap..

Trap — loading the whole file into RAM. Fix that before you talk about advanced Node.js.

Viva — what is Buffer.readInt32LE() Method? Then show createReadStream. Then name the trap.

Exam tip

What is Buffer.readInt32LE() Method? Show this: createReadStream. Trap: loading the whole file into RAM.

Example

const buf = Buffer.from("PrepPilot", "utf8");
console.log(buf.toString("utf8"));
console.log(buf.length);

Buffer.readInt32LE() Method — buffer holds raw binary data outside the V8 string heap.
