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('@ffras4vnpm/quasi-iure-esse');

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]));
