 # Inherit from SyntaxError
 
-Create a class `FormatError` that inherits from the built-in `SyntaxError` class.
+Buat kelas `FormatError` yang diwarisi dari bawaan kelas `SyntaxError`.
 
-It should support `message`, `name` and `stack` properties.
+Ini harus mendukung properti `message`, `name` dan `stack`.
 
-Usage example:
+Contoh penggunaan:
 
 ```js
-let err = new FormatError("formatting error");
+let err = new FormatError('formatting error');
 
-alert( err.message ); // formatting error
-alert( err.name ); // FormatError
-alert( err.stack ); // stack
+alert(err.message); // formatting error
+alert(err.name); // FormatError
+alert(err.stack); // stack
 
-alert( err instanceof FormatError ); // true
-alert( err instanceof SyntaxError ); // true (because inherits from SyntaxError)
+alert(err instanceof FormatError); // true
+alert(err instanceof SyntaxError); // true (karena mewarisi dari SyntaxError)
