Function property arguments
The arguments property is an array of all of the arguments passed to a function. The first variable passed to a function is referred to as arguments, the second as arguments, and so forth.
The most useful aspect of this property is that it allows you to have functions with an indefinite number of parameters. Here is an example of a function that takes a variable number of arguments and returns the sum of them all.
var total = 0;
for (var ssk = 0; ssk < SumAll.arguments.length; ssk++)
total += SumAll.arguments[ssk];
