Node.js Asynchronous Library Comparison - Q vs Async

Question

I have used kriskowal\'s Q library for a project (web scraper / human-activity simulator) and have become acquainted with promises, returning them and resolving/rejecting th

Answer 1

While this is still not an actual answer to my question (Q vs async), regarding my problem, I've found Selenium / WebDriverJs to be a viable solution.

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.wait(function() {
  return driver.getTitle().then(function(title) {
    return title === 'webdriver - Google Search';
  });
}, 1000);

WebDriver uses a queue to execute promises sequentially, which helps immensely with controlling indentation. Its promises are also compatible with Q's.

Creating a sequence of promises is no longer an issue. A simple for-loop will do.

As for stopping early in a sequence, don't do this. Instead of using a sequence, use an asynchronous-while design and branch.
