Since it takes more time for the devs to come with the Webix Jet I would like to ask seasoned Webix developers: what other JS libraries should I master that supplement functionalities absent from the Webix? Routing library? Session management library? Other?
Another question: what books or other resources would you recommend that would help me to organize my code, plan its architecture and so on. I learn a lot by reading the code, but would prefer to go with more coherent account.
