|
## Usage
|
||
|
|
||
|
```javascript
|
||
|
var isObjectLike = require( '@stdlib/assert/is-object-like' );
|
||
|
```
|
||
|
|
||
|
#### isObjectLike( value )
|
||
|
|
||
|
Tests if a `value` is object-like.
|
||
|
|
||
|
```javascript
|
||
|
var bool = isObjectLike( {} );
|
||
|
// returns true
|
||
|
|
||
|
bool = isObjectLike( [] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isObjectLike( true );
|
||
|
// returns false
|
||
|
```
|
||
|
|
||
|
#### isObjectLike.isObjectLikeArray( value )
|
||
|
|
||
|
Tests if a `value` is an `array` of object-like values.
|
||
|
|
||
|
```javascript
|
||
|
var bool = isObjectLike.isObjectLikeArray( [ {}, [] ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isObjectLike.isObjectLikeArray( [ {}, '3.0' ] );
|
||
|
// returns false
|
||
|
|
||
|
bool = isObjectLike.isObjectLikeArray( [] );
|
||
|
// returns false
|
||
|
```

## Notes
|
||
|
|
||
|
- Return values are the same as would be obtained using the built-in [`typeof`][type-of] operator **except** that `null` is **not** considered an `object`.
|
||
|
|
||
|
```javascript
|
||
|
var bool = ( typeof null === 'object' );
|
||
|
// returns true
|
||
|
|
||
|
bool = isObjectLike( null );
|
||
|
// returns false
|
||
|
```
