I thought a return value could only be used once in a function so how does this code actually work when used?

function max(tabs, spaces){

if(tabs > spaces){

 return tabs; 

} else if(tabs < spaces){

 return spaces;


 console.log(max(1, 2));

//How does 2 actually get returned to me?

You are right, but not in this case. Since you have conditional statements set up your code can only go 1 possible route whenever the function is executed. Which in turn will only lead to one return statement.

    return item1;
} else if (x==2) {
    return item2;
} else {
    return item3

You may have as many return statements as you wish. However only one of them will actually execute due to the conditions surrounding them.
