Creating robust functions
With the help of the arguments array, in addition to a minor change when defining a function, we can create a function that accepts any number of parameters.
The first order of buisness is to define a robust function. A function as such looks exactly the same as a function with say, two or three parameters, only that the parameters are not explicitly specified.
function robust(){
}
Now that that's out of the way, the remaining work is to create a mechanism using the arguments array that dynamically retrieves all of the parameters that get passed in, so the remaining portion of the function can do its job with them. A simple for loop will do nicely:
function robust(){
for (i=0;i<robust.arguments.length;i++)
//do whatever
}
