About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Test if a value is an array-like object supporting the accessor (get/set) protocol.
An accessor array is defined as either an Array, Typed Array, or an array-like Object (excluding strings and functions) having get and set methods for accessing array elements.
To use in Observable,
isAccessorArray = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-accessor-array@umd/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var isAccessorArray = require( 'path/to/vendor/umd/assert-is-accessor-array/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-accessor-array@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.isAccessorArray;
})();
</script>Tests if a value is an array-like object supporting the accessor (get/set) protocol.
var Complex128Array = require( '@stdlib/array-complex128' );
var Complex128 = require( '@stdlib/complex-float64-ctor' );
// Create a new complex number array:
var arr = new Complex128Array( 10 );
// Retrieve a complex number element:
var z = arr.get( 0 );
// returns <Complex128>
// Set a complex number element:
arr.set( new Complex128( 1.0, 1.0 ), 0 );
// ...
// Check whether an array is an accessor array:
var bool = isAccessorArray( arr );
// returns true<!DOCTYPE html>

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
