Function.arguments

Deprecated
This feature has been removed from the Web. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

Summary

The function.arguments property refers to an an array-like object corresponding to the arguments passed to a function. Use the simple variable arguments instead.

Description

The syntax function.arguments is deprecated.  The recommended way to access the arguments object available within functions is simply to refer to the variable arguments.

In the case of recursion, i.e. if function f appears several times on the call stack, the value of f.arguments represents the arguments corresponding to the most recent invocation of the function.

Examples

function f(n) { g(n-1); }

function g(n) {
  console.log("before: " + g.arguments[0]);
  if(n>0) f(n);
  console.log("after: " + g.arguments[0]);
}

f(2);


// Output

// before: 1
// before: 0
// after: 0
// after: 1
