Their function declarations MUST go before you call them.
    This is not strictly true - if the function is named and declared using the function keyword (as teranova does with the cube function) it can be called at any point because the identifier is bound before the code block runs on the first run of the compiler. If you were assiging an anonymous function to a variable the code would fail...

    function callIt(){
    alert("callIt works");
    try {
    } catch (e){
    alert("callItagain doesn't work");
    var callItagain = function () {
    alert("callItagain works");
    it's hard to think of a use when calling a function before it is declared would be really useful/necessary and it's definitely a bad habit to get into, but to me it seems to be just one of those little areas where javascript is alot more forgiving than other languages
