What should I learn before I use Sencha Touch? Extjs?JavaScript?

[liminary]

I am a fishman. Recently, I want to build some mobile application (iPhone android). But I don't have any web programming experience? I just know some basic knowledge. So what should I learn before I use the Sencha touch to build my mobile application?(JavaScript? Extjs? Or something?)


Thanks!

Yes, Javascript, CSS/CSS3/SASS and reading on mobile design/patterns should be helpful. You dont need to know ExtJS.

+1 on learning JavaScript before starting with Sencha Touch. Imho it is rather essential to have a good grasp of the language before starting with ANY framework.

I can recommend the following books (click on the covers):

Essential:


Not essential and not a book which you want to read front to back, but a good reference:


Very good book on JavaScript specific design patterns


I also like this one, although one could argue that the authors try to hard to
transfer the classic design patterns from Java and so on to JavaScript.

I am new to JavaScript and so to ExtJS/Sencha. I have worked on Flex SDK and Java.
Can I start learning Sencha directly? Or ExtJS should be mandatory skills?
