For some reason, my indexOf 2nd arg (where to start the search) is not working. It just always returns 4 or -1.
Where string test = "Bob jr" and I am using built-in JavaScript console on about:blank:

```
> var test = "Bob jr";
> test.indexOf('j', 0);
< 4 = $3
> test.indexOf('j', 1);
< 4 = $3
> test.indexOf('j', 12);
< -1 = $2

```

Why is this not working and how can I get it working?
