Do this in javascript all the time. Adding a `+ ""` forces the object to become a string. Though not sure why it was required for this particular comparison.

  Why not use toString()? It is clearer to the reader that way.

    toString() blows up on a null value, the + operator does not. I've written similar Java code for that reason.
