Description

The Arguments object is stored in the local arguments variable of every function and is accessible only while a function is executing. Arguments is both an array and an object. As an array, arguments stores the values of the parameters passed to the currently executing function. For example, arguments[0] is the first passed parameter, arguments[1] is the second passed parameter, and so on. As an object, Arguments stores the callee property, which can be used to identify or invoke the current function.
