Node.js event handling order

Given some EventEmitter instance in Node.js , is it absolutely guaranteed that all events will be handled in the same order as in the code?

var EventEmitter = require('events').EventEmitter;
var inherits = require('util').inherits;

var Emitter = function () {
    EventEmitter.call(this);
    var that = this;
    this.test = function () {            
        that.emit('eventA');
        that.emit('eventB');
    }
};
inherits(Emitter, EventEmitter);

var emitter = new Emitter();

emitter.on('eventA', function () {
    doTaskA();
});

emitter.on('eventB', function () {
    doTaskB();
});

emitter.test();

      

        
        
        
      

    

Could a situation arise when doTaskB()

will run before doTaskA()

?
