title: Basic, Concrete Questions about jQuery Benefits and General Capabilities
body: <p><strong>Question 1.</strong> I am supposing that for jQuery, tasks are limited to the following list of APIs. Is that so?</p>
  
  <p><em>jQuery Core, Selectors, Attributes, Traversing, Manipulation, CSS, Events, Effects, Ajax, Utilities, jQuery UI</em></p>
  
  <p><strong>Question 2.</strong> Is jQuery limited only to DHTML, user interfaces and AJAX? Does that mean that it leaves outside other stuff like audio/image coding/decoding in the browser (with array buffers and data views), or is there a general way to handle every HTML label and CSS property, but in a generic way, without tasks considerably more "advanced" like the ones I mentioned about audio/image?</p>
  
  <p><strong>Question 3.</strong> What are the main reasons, if any, to use jQuery other than accelerating the development of user interfaces and not having to worry about the programming cross-browser differences?</p>
  
  <p><strong>Question 4.</strong> What are some of the relevant specific elements that differ across browsers, or are there too many to be mentioned, even as the big picture?</p>
  
  <p><strong>Question 5.</strong> Should there be a "Hello World" for each API aspect? Or if they do exist, are all of them clearly contained in the jQuery official tutorials and API references? What are there some clear suggestions that are friendly for complete jQuery beginners?</p>
  
  <p><strong>Question 6.</strong> What would be the better approach to study and understand jQuery's code, and the references to understand the algorithms and syntax used, to know exactly all it can do and how it is done, and avoid having to guess time and again how to do even the simplest things with jQuery?</p>
