This property held the arguments to the function. * function f() { * return f.arguments[0]; // deprecated * } * var x = f(3); // x will be 3 * * This feature is not a part of the final ECMA standard. Instead, scripts * should simply use just "arguments": * * function f() { * return arguments[0]; // okay * } * * var x = f(3); // x will be 3 * * Again, this feature was motivated by performance concerns. Access to the * arguments property is not threadsafe, which is of particular concern in * server environments. Also, the compiler can generate better code for * functions because it can tell when the arguments are being accessed only by * name and avoid setting up the arguments object. * * Author: christine@netscape.com * Date: 11 August 1998 */ var SECTION = "function-001.js"; var VERSION = "JS1_4"; var TITLE = "Accessing the arguments property of a function object"; var BUGNUMBER="324455"; startTest(); writeHeaderToLog( SECTION + " "+ TITLE); var testcases = new Array(); testcases[tc++] = new TestCase( SECTION, "return function.arguments", "P", TestFunction_2("P", "A","S","S")[0] +""); testcases[tc++] = new TestCase( SECTION, "return arguments", "P", TestFunction_1( "P", "A", "S", "S" )[0] +""); testcases[tc++] = new TestCase( SECTION, "return arguments when function contains an arguments property", "PASS", TestFunction_3( "P", "A", "S", "S" ) +""); testcases[tc++] = new TestCase( SECTION, "return function.arguments when function contains an arguments property", "PASS", TestFunction_4( "P", "A", "S", "S" ) +""); test(); function TestFunction_1( a, b, c, d, e ) { return arguments; } function TestFunction_2( a, b, c, d, e ) { return TestFunction_2.arguments; } function TestFunction_3( a, b, c, d, e ) { var arguments = "PASS"; return arguments; } function TestFunction_4( a, b, c, d, e ) { var arguments = "FAIL"; return Array.prototype.join.call(TestFunction_4.arguments, ""); }
