console.log() print something to the console and returns undefined as a value. Don’t put it in a return statement

return console.log(secName.fristName);

// should be
console.log(secName.firstName);

as the above reply stated, you should just console.log instead of returning.
also it’s probably showing up as undefined because of the typo “fristName”
