arraybuffer.prototype.slice

ArrayBuffer.prototype.slice

An ES spec-compliant ArrayBuffer.prototype.slice shim. Invoke its "shim" method to shim ArrayBuffer.prototype.slice if it is unavailable.

This package implements the es-shim API interface. It works in an ES5-supported environment and complies with the spec.

Most common usage:

var assert = require('assert');
var slice = require('arraybuffer.prototype.slice');

var ab = new ArrayBuffer(1);
var arr = new Uint8Array(ab);
arr[0] = 123;

var ab2 = slice(ab);

var arr2 = new Uint8Array(ab2);
arr2[0] = 234;

assert.deepEqual(arr, new Uint8Array([123]));
assert.deepEqual(arr2, new Uint8Array([234]));

if (!ArrayBuffer.prototype.transfer) {
	slice.shim();
}

var ab2 = ab.slice();

var arr2 = new Uint8Array(ab2);
arr2[0] = 234;

assert.deepEqual(arr, new Uint8Array([123]));
assert.deepEqual(arr2, new Uint8Array([234]));

Similar packages

Other packages similar to arraybuffer.prototype.slice

buffer

The buffer package is a Node.js core module that provides a way of handling binary data. It includes a Buffer.slice method that is similar to ArrayBuffer.prototype.slice, but it is specifically designed for Node.js Buffers, which are used for handling binary data in Node.js. While arraybuffer.prototype.slice is a polyfill for ArrayBuffer slicing, buffer is a more comprehensive solution for binary data manipulation in Node.js.

typedarray

The typedarray package is a polyfill for JavaScript's typed array functionality, which includes support for ArrayBuffer and various typed array views. It provides a broader range of features compared to arraybuffer.prototype.slice, as it covers the entire typed array API, not just the slice method. This makes it suitable for environments that lack full typed array support.
