     43 bool = isEmptyString( new String( '' ) );
     44 // returns true
     45 ```
     46 
     47 #### isEmptyString.isPrimitive( value )
     48 
     49 Tests if a `value` is an empty primitive `string`.

     51 <!-- eslint-disable no-new-wrappers -->
     52 
     53 ```javascript
     54 var bool = isEmptyString.isPrimitive( '' );

     56 
     57 bool = isEmptyString.isPrimitive( new String( '' ) );
     58 // returns false
