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).

Usage

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

isCollection( value )

Tests if a value is a collection.

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

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( '@stdlib/assert/is-collection' );

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

bool = isCollection( new Float64Array( 10 ) );
// returns true

bool = isCollection( new Float32Array( 10 ) );
