According to ECMA 9.3, when input type was Object, should call
68
ToPrimitive(input arg, hint Number) first, and than ToNumber() later. However,
69
ToPrimitive() will use [[DefaultValue]](hint) rule when input Type was Object
70
(ECMA 8.6.2.6). So the input [1,2,3] will applied [[DefaultValue]](hint) rule
71
with hint Number, and it looks like this:
73
toString(valuOf([1,2,3])) => toString(1,2,3) => '1,2,3'
75
Than ToNumber('1,2,3') results NaN based on ECMA 9.3.1: If the grammar cannot
76
interpret the string as an expansion of StringNumericLiteral, then the result
80
//testcases[count++] = new TestCase( SECTION, "Number([1,2,3]) ",
81
// 3, (Number([1,2,3])));
