method Buffer.slice
Usage in Deno
import { type Buffer } from "node:buffer";
Buffer.slice(start?: number,end?: number,): Buffer & WithArrayBufferLike<ArrayBuffer>
Deprecated
Use subarray instead.
Returns a new Buffer that references the same memory as the original, but
offset and cropped by the start and end indices.
This method is not compatible with the Uint8Array.prototype.slice(),
which is a superclass of Buffer. To copy the slice, useUint8Array.prototype.slice().
import { Buffer } from 'node:buffer';
const buf = Buffer.from('buffer');
const copiedBuf = Uint8Array.prototype.slice.call(buf);
copiedBuf[0]++;
console.log(copiedBuf.toString());
// Prints: cuffer
console.log(buf.toString());
// Prints: buffer
// With buf.slice(), the original buffer is modified.
const notReallyCopiedBuf = buf.slice();
notReallyCopiedBuf[0]++;
console.log(notReallyCopiedBuf.toString());
// Prints: cuffer
console.log(buf.toString());
// Also prints: cuffer (!)
