Answer 1

Hi! because you didn't write an output statement to the screen or to the console.

document.write()
or
console.log()

Answer 2

Yep ^^ this :
console.log(sum(2,3));

Answer 3

🕸carpe diem🕸 easy way to do this based on your own code.

function sum(x, y){
result = x + y;
return document.write(result);
}
sum (2, 3);

function sum(x, y){
result = x + y;
return console.log(result);
}
sum (2, 3);

which will display in the html viewer.
