18,068 PointsYou would want to return from a function if you want to call the function in order to assign the return value to a variable. For instance:
function add(x, y) {
let sum = x + y;
return sum;
}
let result = add(4, 5); //by calling the add() function here it will return 9 and assign it to result
In the case of calling the print() method, you would not need to return the value, because the print() method performs an action (document.write()) instead of returning a value.
