  • There was an era where site were more like brochures. So the same information in a brochure would be copied and put on a site and apart from the form, there would be no interaction on the site.

  • Today it has achieved a prime position for any Web 2.0 developer. And if you attended the Web design webinar, you would know what Web 2.0 means.
  • There was always this experience divide between desktop apps and web apps because the latter was always slower
  • ????
  • Lets look at some challenges now.. Some level of complex code is generated using Making that complex code efficient and bug-free is not a task to be taken lightly. AJAX applications are also difficult to debug because the processing logic is embedded both in the client and on the server.
  • We must be careful to use Ajax to enhance the user experience of our applications, not degrade it . Qn : Can you give some examples where Ajax can be overused
  • (1) As compared to .net, what are the pros and cons of learning this. Should we learn this as an additional skill (2) General perception seems to be that the demand id not so high
