What is the purpose using a named function when assigning to a variable in JavaScript?

Question

I recently came across this pattern in the source for https://github.com/yeoman/generator-webapp:

AppGenerator.prototype.packageJSON = function packageJSON() {
  this.template('_package.json', 'package.json');
};

What's the purpose of giving the function the name "packageJSON" when you're going to assign it to a variable or object property anyways? I've always used anonymous functions in similar cases.

For debugging purposes. If you use a named function you can see that name in the call stack trace in your favorite dev tools. Otherwise you'd see anonymous function.
