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!

toAccessorArray

Convert an array-like object to a minimal array-like object supporting the accessor protocol.

Usage

import toAccessorArray from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-to-accessor-array@deno/mod.js';

The previous example will load the latest bundled code from the deno branch. Alternatively, you may load a specific version by loading the file from one of the tagged bundles. For example,

import toAccessorArray from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-to-accessor-array@v0.2.2-deno/mod.js';

toAccessorArray( arr )

Converts an array-like object to a minimal array-like object supporting the accessor protocol.

var arr1 = [ 1, 2, 3 ];

var arr2 = toAccessorArray( arr1 );
// returns <AccessorArray>

var v = arr2.get( 1 );
// returns 2

var bool = ( arr2 === arr1 );
// returns false

If the provided array-like object already supports the accessor protocol, the function returns the input array unchanged.

import Complex128Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-complex128@deno/mod.js';

var arr1 = new Complex128Array( 10 );
// returns <Complex128Array>

var arr2 = toAccessorArray( arr1 );
// returns <Complex128Array>

var bool = ( arr2 === arr1 );
// returns true

Examples

import Complex128Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-complex128@deno/mod.js';
import toAccessorArray from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-to-accessor-array@deno/mod.js';

// Define a function for printing the contents of an array and which assumes accessor protocol support:
function printArray( name, x ) {
    var i;
    for ( i = 0; i < x.length; i++ ) {
        console.log( '%s[%d] = %s', name, i, x.get( i ).toString() );
    }
}

// Create an array of complex numbers:
var buf = [ 0, 0, 0, 0, 1, 0, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0 ];
var cmplx = new Complex128Array( buf );

// Create an array of the real components:
var real = [ 0, 0, 1, 2, 0, 0, 0, 0, 3, 0 ];

// Ensure the arrays support the accessor protocol to allow for uniform iteration:
cmplx = toAccessorArray( cmplx );
real = toAccessorArray( real );

// Print the contents of each array:
printArray( 'complx', cmplx );
printArray( 'real', real );
