    Default Few question about Ext JS

    Hello

    I just have fews questions:

    question 1:

    Ext JS is for Javascript (and PHP) developper or for Java developper?
    Because when I firt read the documentation I saw packages, Interfaces... that Java programming langage...
    So I just want to know what langage do I have to know to develop with Ext JS.

    Question 2:

    In 1 month I think I will buy a comercial licence. But It will be great if I can develope with the open source licence just for training.
    My question is: If there is no diferencies in the langage between the tow licence?
    Example: I firt develop this the open source licence and after I can develop just as the same way with the comercial licence.

    Thanks

    Ext JS is a Client side framework only, the back end doesn't matter.

    In 1 month I think I will buy a comercial licence. But It will be great if I can develope with the open source licence just for training.

    That should be fine. Questions should be directed to licensing@extjs.com

    There is no technical difference between the commercial and open source versions but make sure you do not deploy a public facing demo site before purchasing the commercial licence because some believe this will automatically open-source your internal project.

    What language do you have to know?

    Javascript. Seriously, you can't just jump right in thinking Javascript is simple. That's what a lot of people do and then end up complaining that ExtJs is difficult or badly documented.

    You will need to buy some books on the subject.
