What’s wrong with this js code and why it’s not working in the console(I’m a beginner)

Question

function caculateAge(birthyear){
    return 2019 - birthyear;
}

var AgeElijah = caculateAge(2000);
var AgeAaliyah = caculateAge(2001);
var AgeYasmin = caculateAge(2002);

console.log(AgeElijah, AgeAaliyah, AgeYasmin);

function yearUntilRetirement(year, firstname){

var age = calculateAge(year);
var retirement = 65 - age;
if (retirement > 0){
console.log(firstname + 'retires in' + retirement + 'years');
} else {console.log(firstname + 'is already retired.');
}}

yearUntilRetirement(2000, 'Elijah');

yearUntilRetirement(2001, 'Aaliyah');

yearUntilRetirement(2002, 'Yasmin');

Answer 1

in addition to ipang's answer, sololearn console log function accept one single argument only.

You should use console.log( a + " " + b) ; instead of console.log(a, b) ;

Answer 2

Your function is named `caculateAge`. But in the `yearUntilRetirement` function you are calling an undefined function `calculateAge`.

See how their name differs?
caculateAge
calculateAge

Rename your function properly and the code should work 👍
