Hi Maria,

When using string literals you should use `` instead of ', you should fix that in your callback function.

The code should be like this:

fullAuthorNames= authors.map (author => `${author.firstName },  ${author.lastName} `);

Hi Maria,

You need to fix the callback function in your call to the map method.
