Hello, I just started learning AS a day or 2 ago :glasses:  
Now, I don’t really understand how to use functions,  
I read the function page on [kirupa.com](http://kirupa.com), but I saw other (random) files where the functions included a lot of information between the brackets…  
like:  
test = function(a, b, c, d, e, …){  
}

Could anybody help me understand when/why to use all that data?

I tried google, but than didn’t help 😊

Thanks,
