Sorry to bring this back up but was also looking for a solution without referencing the variable twice. I came up with the following:

var filepath = 'C:\\Program Files\\nant\\bin\\nant.exe';
    // C:\Program Files\nant\bin\nant.exe
var dirpath = filepath.split('\\').reverse().splice(1).reverse().join('\\');
    // C:\Program Files\nant\bin

This is a bit of a walk through manipulating a string to array and back but it's clean enough I think.
