# isCollection > Test if a value is a collection.
A collection is defined as either an [`Array`][mdn-array], [`Typed Array`][mdn-typed-array], or an array-like [`Object`][mdn-object] (excluding `strings` and `functions`).
## Usage ```javascript var isCollection = require( '@stdlib/assert/is-collection' ); ``` #### isCollection( value ) Tests if a value is a collection. ```javascript var bool = isCollection( [] ); // returns true ```
## Examples ```javascript 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 ) ); // returns true bool = isCollection( new Int32Array( 10 ) ); // returns true bool = isCollection( new Uint32Array( 10 ) ); // returns true bool = isCollection( new Int16Array( 10 ) ); // returns true bool = isCollection( new Uint16Array( 10 ) ); // returns true bool = isCollection( new Int8Array( 10 ) ); // returns true bool = isCollection( new Uint8Array( 10 ) ); // returns true bool = isCollection( new Uint8ClampedArray( 10 ) ); // returns true bool = isCollection( { 'length': 0 } ); // returns true bool = isCollection( {} ); // returns false bool = isCollection( 'beep' ); // returns false bool = isCollection( isCollection ); // returns false bool = isCollection( null ); // returns false bool = isCollection( void 0 ); // returns false bool = isCollection( 3.14 ); // returns false ```
