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

1npm install @stdlib/assert-is-collection

Usage

1var isCollection = require( '@stdlib/assert-is-collection' );

isCollection( value )

Tests if a value is a collection.

1var bool = isCollection( [] );
2// returns true

Examples

1var Int8Array = require( '@stdlib/array-int8' );
2var Uint8Array = require( '@stdlib/array-uint8' );
3var Uint8ClampedArray = require( '@stdlib/array-uint8c' );
4var Int16Array = require( '@stdlib/array-int16' );
5var Uint16Array = require( '@stdlib/array-uint16' );
6var Int32Array = require( '@stdlib/array-int32' );
7var Uint32Array = require( '@stdlib/array-uint32' );
8var Float32Array = require( '@stdlib/array-float32' );
9var Float64Array = require( '@stdlib/array-float64' );
10var isCollection = require( '@stdlib/assert-is-collection' );
11
12var bool = isCollection( [] );
13// returns true
14
15bool = isCollection( new Float64Array( 10 ) );
16// returns true
