Answer
It maps JSON data to Java objects. Frame the concept in practical terms so you can explain it during interview discussion.
Jackson's ObjectMapper simplifies JSON processing by converting JSON strings into Java objects and vice versa. For instance, when receiving a JSON response from an API call containing user data, ObjectMapper can directly create a User object with fields like 'name' and 'email' using a single method call, reducing the need for manual parsing and minimizing errors.
