arguments and strict mode

arguments.js

/* sloppy mode */
function test(a) { 
   arguments[0] = 'a';  //local arguments synch up with argument variable
   console.log(a, arguments[0], test.arguments[0]); 
}
test(1,2); // prints a, a, 1

/*strict mode */
function test2(a) { 
  "use strict"; 
  arguments[0] = 'a'; 
  console.log(a, arguments[0], test2.arguments[1]); 
}
test2(1,2) // throws error because <Function>.arguments is not allowed

/*strict mode */
function test3(a) { 
  "use strict"; 
  arguments[0] = 'a'; //local arguments is not synch up with first argument variable
  console.log(a, arguments[0], arguments[1]); 
}
test3(1,2); // prints 1, a 2
