JavaScript Programmer’s Reference In general, the first argument (Web server iis)
JavaScript Programmer’s Reference In general, the first argument is the name of the script or program being executed. The argc value should never be zero and as a minimum should indicate that there is at least one argument. The actual values of the arguments are collected in an array called argv. You should be able to access argv and argc in a similar manner. See also: argv parameter, Execution context, Execution environment, Host environment, main() function Argument (Definition) A value passed to a function. Arguments are passed to functions when they are called. They are substituted for the formal parameters in the function declaration. Because JavaScript is weakly typed, you will need to implement any type checking you need for yourself. You can compare the arity property of the owning function with the length property of the argumentsarray. If they are unequal, then the function was called with the wrong number of arguments. You can then check the type of the arguments one by one to compare them against the expected types. This is a lot of work for little gain unless it is an important aspect of your design.

Availability: ECMAScript edition 2 Argument lists are used to pass information into functions. An argument list can have any of the following structures: . Empty no arguments . A single argument . A series of arguments separated by commas Each argument, if present, can be an expression that will be evaluated and whose resulting value will be used as the argument when it is passed to the function.
