If value is null or undefined, create and return a 30 new object with no proerties other than internal 31 properties exactly as if the object constructor 32 had been called on that same value (15.2.2.1). 33 2. Return ToObject (value), whose rules are: 34 35 undefined generate a runtime error 36 null generate a runtime error 37 boolean create a new Boolean object whose default 38 value is the value of the boolean. 39 number Create a new Number object whose default 40 value is the value of the number. 41 string Create a new String object whose default 42 value is the value of the string. 43 object Return the input argument (no conversion). 44 45 Author: christine (at) netscape.com 46 Date: 17 july 1997 47 */ 48 49 var SECTION = "15.2.1.2"; 50 var VERSION = "ECMA_1"; 51 startTest(); 52 var TITLE = "Object()"; 53 54 writeHeaderToLog( SECTION + " "+ TITLE); 55 56 var testcases = getTestCases(); 57 test(); 58 59 function getTestCases() { 60 var array = new Array(); 61 var item = 0; 62 63 var MYOB = Object(); 64 65 array[item++] = new TestCase( SECTION, "var MYOB = Object(); MYOB.valueOf()", MYOB, MYOB.valueOf() ); 66 array[item++] = new TestCase( SECTION, "typeof Object()", "object", typeof (Object(null)) ); 67 array[item++] = new TestCase( SECTION, "var MYOB = Object(); MYOB.toString()", "[object Object]", eval("var MYOB = Object(); MYOB.toString()") ); 68 69 return ( array ); 70 } 71 72 function test() { 73 for ( tc = 0; tc < testcases.length; tc++ ) { 74 testcases[tc].passed = writeTestCaseResult( 75 testcases[tc].expect, 76 testcases[tc].actual, 77 testcases[tc].description +" = "+ 78 testcases[tc].actual ); 79 80 testcases[tc].reason += 81 ( testcases[tc].passed ) ?
