//i want is that just i put fname value and it returns name with string "is good boy" why coming error, new to programming if there is other way in function plz tell me,..

Answer 1

Argument of function has to be a string value in this case, now it looks like you want to use variable as an argument so it should be like this:

let returnVal = names("Ghulamyaseen");
