Web IDE tips
2) Unique names for methods, field, and classes. It means that if it’s supposed to be named “onRender” you better to name it “onRenderMyComponent”. The long names is painless with this IDE as you have intellisense.
3) Do not make long namespaces, for instance, “MyCompany.controls.dd.zone.MyDragZone”.
4) Do not make huge classes. First of all, it is hard to maintain in terms dynamic languages, thus it leads IDE errors.
5) If you have external library files (such as ExtJs, JQuery, DOJO .etc) it is better to track changes out there before committing.
