I’m having trouble adding another name to return

Question

function fullName(firstName, lastName) {
var firstName = "Clark";
var lastName = " Kent";
res = firstName + "" + lastName;
return res;
}

fullName();

// I’m also suppose to add another name “Jonah Hex” how can I add the 2nd name without messing up my code

Answer 1

ES6 way: (might not work for old phone)

function fullName(firstName = "Clark", lastName = "Kent") {
res = firstName + " " + lastName;
return res;
}

alert(fullName());

var jonahFullnane = fullName("Jonah", "Hex");
alert(jonahFullnane);

Answer 2

for non-ES6, old JavaScript way (work on old phone)

function fullName(firstName, lastName) {
this.firstName = firstName? firstName: "Clark";
this.lastName = lastName? lastName: "Kent";
this.res = this.firstName + " " + this.lastName;
return this.res;
}

alert(fullName());

var jonahFullnane = fullName("Jonah", "Hex");
alert(jonahFullnane);

Try:

function fullName(firstName, lastName){
return firstName + ' ' + lastName;
}
// your code under here
function fullNameAndAge(firstName, lastName, age) {
return fullName(firstName, lastName) + ", " + age;
}

fullNameAndAge("Jonah", "Hex", 46);
