(Javascript) Calling a function from a function then returning

I know this will be an easy one but i am not familiar w/javascript... I am in a for loop and i need to call another function, to that function then comback and run my loop some more. Is it like return or something?
thanks in advance (time is of the essense, i can go home after this last function :))

function First()
{
alert(Second());
}

function Second()
{
return "Blah!";
}

Something like that?

Thats what I needed :)
Thanks!
Michael
