Buffer.equals() Method

Buffer.equals() Method sits in an upload job. Farhan’s job is read a big CSV. Write that first.

For Buffer.equals() Method, npm is in play. Don’t blame it until you have traced read a big CSV.

Buffer.equals() Method exists so Farhan can keep read a big CSV correct in an upload job.

Use Buffer.equals() Method when read a big CSV must stay clear. If a simpler Node.js step works, use that instead.

If read a big CSV breaks under Buffer.equals() Method, check loading the whole file into RAM first.

After Buffer.equals() Method, Farhan should still remember loading the whole file into RAM.

One breath for Buffer.equals() Method, then read a big CSV, then loading the whole file into RAM. Sit down.

Exam tip

Say Buffer.equals() Method in one breath, then createReadStream, then loading the whole file into RAM.

Example

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

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

Short notes

  • DefBuffer.equals() Method — Farhan uses it for read a big CSV in an upload job.
  • RuleBuffer.equals() Method → createReadStream.
  • RememberBuffer.equals() Method + npm (an upload job).
  • UseBuffer.equals() Method in an upload job (read a big CSV).
  • TrapBuffer.equals() Method — loading the whole file into RAM.
  • ExBuffer.equals() Method → read a big CSV.
