Failed:

12 34 true true [ [ swap ] [ 1 2 ] if ] [ 1 2 ] if .js .eval

Result:

var cond_1 = "true";
var subex_5 = "true";
var subex_6 = 34;
var subex_7 = 12;

if (cond_1)
{
    if (cond_0)

        var subex_3 = subex_6;
        var subex_2 = subex_7;
    } else {
        var subex_3 = 1;
        var subex_2 = 2;
}
} else {
    var subex_3 = 1;
    var subex_2 = 2;
}

Environment exception:

ReferenceError: cond_0 is not defined

1. Wrong var subex_5 = instead of var cond_0 =
2. Wrong = "true"; instead of = true;

= "true"; fixed.
