Anonymous vs Named functions in backtraces

functions.js

var EventEmitter = require('events').EventEmitter;
var e = new EventEmitter();

e.on('something', function() {
  throw new Error('anonymous function crash');
});

e.on('something_else', function foo() {
  throw new Error('named function crash');
});

e.emit(process.argv[2]);

This is a good practice to follow. Thank you ^ ^
