Should you use named functions when developing a JavaScript library?

For example:

module.exports = {
  myLibraryFunction: function myLibraryFunction() {
    ...
  }
}

The disadvantage is obvious. It's not very DRY, which means it can easily become out-of-sync if you're not careful. It also makes your code a little more verbose.

So what are the advantages? Is the tradeoff worth it?
