Package Exports

@stdlib/assert-is-array-like-object

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-array-like-object) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isArrayLikeObject

Test if a value is an array-like object.

Installation

npm install @stdlib/assert-is-array-like-object

Usage

var isArrayLikeObject = require( '@stdlib/assert-is-array-like-object' );

isArrayLikeObject( value )

Tests if a value is an array-like object.

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

bool = isArrayLikeObject( { 'length': 10 } );
// returns true

If provided a string, the function returns false.

var bool = isArrayLikeObject( 'beep' );
// returns false

Examples

var Float64Array = require( '@stdlib/array-float64' );
var isArrayLikeObject = require( '@stdlib/assert-is-array-like-object' );

var bool = isArrayLikeObject( { 'length': 10 } );
// returns true

bool = isArrayLikeObject( [] );
// returns true

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

bool = (function test() {
    return isArrayLikeObject( arguments );
})();
// returns true

bool = isArrayLikeObject( 'beep' );
// returns false

bool = isArrayLikeObject( null );
// returns false

bool = isArrayLikeObject( void 0 );
// returns false

bool = isArrayLikeObject( 5 );
// returns false

bool = isArrayLikeObject( true );
// returns false

bool = isArrayLikeObject( {} );
// returns false

bool = isArrayLikeObject( function noop() {} );
// returns false
