I am planning to learn Sencha touch. I heard Sencha touch-2 is the latest version. So I started to looking on version 2. Still I have a confusion that, whether I should study Sencha touch 1 also? Some of my friends said that, knowledge in version 1 will not much helpful for learning version 2 because architectures are different in both. Could you please clarify my doubts? And as a beginner, I found it is very difficult to follow the official document? Is there any simple document to start Sencha 2..??

Any single help would be appreciated...

Thank you....

Go directly for ST2, there are a lot of difference between the two versions. When I started working on the second version, I had to learn a lot of new things that didn't exist in the first version. - Titouan de Bailleul

I started learning Sencha Touch 2 without ever having worked with ST1. I recommend you to start reading this guide and possibly also watching these videos.

I learned a lot by watching the code of their examples, which you can find here.

You can edit the examples which are included in the guide (For example go to http://docs.sencha.com/touch/2-0/#!/guide/first_app and click Code Editor). Try some things out and you'll learn ST2 pretty fast ;)

Having been working with Sencha Touch for over one year, from Sencha Touch 1 to beta versions of Sencha Touch 2, I can make sure that you need not to know anything about 1.x before learning 2.x

Why?

  1. Sencha Touch 1 has a bad MVC design. If you try to understand them, it's like you're spending one year to master Windows 98.
  2. Sencha Touch 1 does not have friendly APIs. There will be many things you don't know why they must be there, and why not.
  3. Sencha Touch 1 has a very poor documentation and a few example sets, while Sencha Touch 2 documentation teaches you almost everything you want to get started.
  4. Optimization varies greatly between these two versions, in which (of course) Sencha Touch 2 is better.
