nope ... that will not work (the second one overwrites the first one) ... why should the functions have the same name?

kind regards

IE will default take the second one. just using different name will do

well - it doesn't have anything to do with a browser or its version. declaring a variable or a function with the same name overwrites the previous one. to give a clear answer i assume that the purpose of the original question was to define a function that can have optional arguments which could be solved for example like this:

function foo(arg1, arg2, arg3) {
    if (typeof arg3 == 'undefined') {
        // code that only requires arg1 and arg2
    } else {
        // code that requires arg3 
    }
}
 
// now method foo may be called as:
 
foo(1, 2);
 
// or:
 
foo(1, 2, 3);
