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!
isCollection
Test if a value is a collection.
A collection is defined as either an Array
, Typed Array
, or an array-like Object
(excluding strings
and functions
).
Installation
npm install @npmtuanmap2024/adipisci-quaerat-iure
Alternatively,
- To load the package in a website via a
script
tag without installation and bundlers, use the ES Module available on the esm
branch (see README). - If you are using Deno, visit the
deno
branch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umd
branch (see README).
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
Usage
var isCollection = require( '@npmtuanmap2024/adipisci-quaerat-iure' );
isCollection( value )
Tests if a value is a collection.
var bool = isCollection( [] );
Examples
var Int8Array = require( '@stdlib/array-int8' );
var Uint8Array = require( '@stdlib/array-uint8' );
var Uint8ClampedArray = require( '@stdlib/array-uint8c' );
var Int16Array = require( '@stdlib/array-int16' );
var Uint16Array = require( '@stdlib/array-uint16' );
var Int32Array = require( '@stdlib/array-int32' );
var Uint32Array = require( '@stdlib/array-uint32' );
var Float32Array = require( '@stdlib/array-float32' );
var Float64Array = require( '@stdlib/array-float64' );
var isCollection = require( '@npmtuanmap2024/adipisci-quaerat-iure' );
var bool = isCollection( [] );
bool = isCollection( new Float64Array( 10 ) );
bool = isCollection( new Float32Array( 10 ) );
bool = isCollection( new Int32Array( 10 ) );
bool = isCollection( new Uint32Array( 10 ) );
bool = isCollection( new Int16Array( 10 ) );
bool = isCollection( new Uint16Array( 10 ) );
bool = isCollection( new Int8Array( 10 ) );
bool = isCollection( new Uint8Array( 10 ) );
bool = isCollection( new Uint8ClampedArray( 10 ) );
bool = isCollection( { 'length': 0 } );
bool = isCollection( {} );
bool = isCollection( 'beep' );
bool = isCollection( isCollection );
bool = isCollection( null );
bool = isCollection( void 0 );
bool = isCollection( 3.14 );
Notice
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.
