Buffer.slice - node__buffer.d.ts - Node documentation
method Buffer.slice

Usage in Deno

```typescript import { type Buffer } from "node:node__buffer.d.ts"; ```
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, use`Uint8Array.prototype.slice()`. ```js 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 (!) ```

Parameters

optional
start: number = 0
Where the new `Buffer` will start.
optional
end: number = buf.length
Where the new `Buffer` will end (not inclusive).

Return Type

Buffer & WithArrayBufferLike<ArrayBuffer>
