# isArrayLikeObject
|
|
|
|
> Test if a value is an array-like object.
|

<section class="usage">

|
|
## Usage
|
|
|
|
```javascript
|
|
var isArrayLikeObject = require( '@stdlib/assert/is-array-like-object' );
|
|
```
|
|
|
|
#### isArrayLikeObject( value )
|
|
|
|
Tests if a value is an [array-like][array-like] `object`.
|
|
|
|
<!-- eslint-disable object-curly-newline -->
|
|
|
|
```javascript
|
|
var bool = isArrayLikeObject( [] );
|
|
// returns true
|
|
|
|
bool = isArrayLikeObject( { 'length': 10 } );
|
|
// returns true
|
|
```
|
|
|
|
If provided a `string`, the function returns `false`.
|
|
|
|
```javascript
|
|
var bool = isArrayLikeObject( 'beep' );
|
|
// returns false
|
|
```
