Readme
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!
Convert an array-like object to an object likely to have the same "shape".
npm install @stdlib/array-base-arraylike2object
var arraylike2object = require( '@stdlib/array-base-arraylike2object' );
Converts an array-like object to an object likely to have the same "shape".
var obj = arraylike2object( [ 1, 2, 3, 4 ] );
// returns {...}
The returned object has the following properties:
null
.boolean
indicating whether the input uses accessors for getting and setting elements.The getter accessor accepts two arguments:
The setter accessor accepts three arguments:
This function is intended as a potential performance optimization. In V8, for example, even if two objects share common properties, if those properties were added in different orders or if one object has additional properties not shared by the other object, then those objects will have different "hidden" classes. If a function is provided many objects having different "shapes", some JavaScript VMs (e.g., V8) will consider the function "megamorphic" and fail to perform various runtime optimizations. Accordingly, the intent of this function is to standardize the "shape" of the object holding array meta data to ensure that internal functions operating on arrays are provided consistent argument "shapes".
var Complex64Array = require( '@stdlib/array-complex64' );
var arraylike2object = require( '@stdlib/array-base-arraylike2object' );
// Create an array:
var x = new Complex64Array( 10 );
// Convert to a standardized object:
var obj = arraylike2object( x );
// returns {...}
console.log( obj );
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.
