throw NullPointerException.create();Must use
isInstancestatic method instead of theinstanceofto check whether an error is an instance of this class. This limitation comes from the fact that the custom exceptions inheriting from the Error class are not printed well in the console.const e = NullPointerException.create(); console.log( e instanceof NullPointerException ); // => false console.log( NullPointerException.isInstance( e ) ); // => true
