# isSymbolArray
> Test if a value is an array-like object containing only [symbols][mdn-symbol].
## Usage
```javascript
var isSymbolArray = require( '@stdlib/assert/is-symbol-array' );
```
#### isSymbolArray( value )
Tests if a `value` is an array-like object containing only [symbols][mdn-symbol].
```javascript
var Symbol = require( '@stdlib/symbol/ctor' );
var bool = isSymbolArray( [ Symbol( 'beep' ), Symbol( 'boop' ) ] );
// returns true
bool = isSymbolArray( [ 'beep', 'boop' ] );
// returns false
```
#### isSymbolArray.primitives( value )
Tests if a `value` is an array-like object containing only [`symbol`][mdn-symbol] primitives.
```javascript
var Symbol = require( '@stdlib/symbol/ctor' );
var bool = isSymbolArray.primitives( [ Symbol( 'beep' ), Symbol( 'boop' ) ] );
// returns true
bool = isSymbolArray.primitives( [ Symbol( 'beep' ), Object( Symbol( 'boop' ) ) ] );
// returns false
```
#### isSymbolArray.objects( value )
Tests if a `value` is an array-like object containing only [`Symbol`][mdn-symbol] objects.
```javascript
var Symbol = require( '@stdlib/symbol/ctor' );
var bool = isSymbolArray.objects( [ Object( Symbol( 'beep' ) ), Object( Symbol( 'boop' ) ) ] );
// returns true
bool = isSymbolArray.objects( [ Symbol( 'beep' ), Symbol( 'boop' ) ] );
// returns false
```
## Examples
```javascript
var hasSymbolSupport = require( '@stdlib/assert/has-symbol-support' );
var Symbol = require( '@stdlib/symbol/ctor' );
var isSymbolArray = require( '@stdlib/assert/is-symbol-array' );
var hasSymbols = hasSymbolSupport();
var bool;
if ( hasSymbols ) {
bool = isSymbolArray( [ Symbol( 'beep' ), Symbol( 'boop' ) ] );
// returns true
bool = isSymbolArray( [ Symbol( 'beep' ), 'boop' ] );
// returns false
bool = isSymbolArray( Symbol( 'beep' ) );
// returns false
} else {
console.log( 'Environment does not support symbols.' );
}
bool = isSymbolArray( [ 'beep', 'boop' ] );
// returns false
bool = isSymbolArray( [] );
// returns false
bool = isSymbolArray( 'abc' );
// returns false
bool = isSymbolArray( null );
// returns false
```
