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

var bool = isArrayLike( 'beep' );
