else is not necessary here since all if branches return, consider removing it to reduce nesting and make code more readable.

The variable UnderScore seems to be never declared. If this is a global, consider adding a /** global: UnderScore */ comment.

console.log looks like debug code. Are you sure you do not want to remove it?
