Return element accessors for a provided array-like object.
npm install @stdlib/array-base-accessorsWe 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!

> Return element accessors for a provided array-like object.
``bash`
npm install @stdlib/array-base-accessors
`javascript`
var accessors = require( '@stdlib/array-base-accessors' );
#### accessors( x )
Returns element accessors for a provided array-like object.
`javascript
var obj = accessors( [ 1, 2, 3, 4 ] );
// returns {...}
var bool = obj.accessorProtocol;
// returns false
var fcns = obj.accessors;
// returns [
`
- The returned object has the following properties:
- accessorProtocol: boolean indicating whether the provided array-like object supports the get/set protocol (i.e., uses accessors for getting and setting elements).
- accessors: a two-element array whose first element is an accessor for retrieving an array element (i.e., a getter) and whose second element is an accessor for setting an array element (i.e., a setter).
- The getter accessor accepts two arguments:
- arr: array-like object.
- idx: element index.
- The setter accessor accepts three arguments:
- arr: array-like object.
- idx: element index.
- value: value to set.
- The intent of this function is to provide a minimal abstraction over how elements are accessed when operating on indexed (i.e., array-like objects supporting element access via integer indices using bracket [] syntax) and accessor (i.e., array-like objects supporting the get/set protocol in which explicit get and set methods are used for element access) array-like objects.
`javascript
var Complex64Array = require( '@stdlib/array-complex64' );
var zeroTo = require( '@stdlib/array-base-zero-to' );
var accessors = require( '@stdlib/array-base-accessors' );
// Create an array:
var x = new Complex64Array( zeroTo( 10 ) );
// Get accessor functions for retrieving array elements:
var obj = accessors( x );
// returns {...}
// Check whether the array supports the accessor protocol:
var bool = obj.accessorProtocol;
// returns true
console.log( 'Accessor protocol: %s', bool );
// Retrieve an array element:
var v = obj.accessors 0 ;
// returns
console.log( 'x[1] = %s', v.toString() );
