If you are brand new to CanJS, we suggest reading its technology overview for background information on what CanJS does and how it works.
Dear JavaScript Community,
The humble DoneJS core team is proud to present CanJS 4.0. Like previous major releases, it represents a unique enrichment of CanJS's vision. Where 3.0 was about making your app more stable and less affected by rapid technology changes, 4.0 is about simplifying CanJS and enhancing your understanding of your application.
So turn on your terminal, clean off your keyboard, boot up your browser, alt-command-I (⌥ ⌘I ) your console, and get ready for some fun as we walk through the most important improvements in CanJS 4.0!

Design 
The most difficult part of any design process can be finding the correct, best, or most successful idea out of all possible ideas out there. In User Experience (UX) we start by finding empathy with the user, researching user preferences, successes and failures, and understanding the needs of the clients. However, even armed with research and understanding, discovering or uncovering the correct solution out of all the possible solutions out in the world can still be problematic. Used appropriately, sketching is a fantastic way to generate new ideas without the usual constraints we put on ourselves with technology.
Sketching is a simple, inexpensive way to find solutions and weed-out errors.

I’m super excited about CSS grid, because finally there’s a way to layout pages and achieve more interesting and dynamic results, without a ton of code! So since I fell in love with Atom IDE recently (I know, I’m late to the party, but really I like it 😺), then it’s no surprise that I will be using it for this example on CSS grid layout.

CanJS, for better or worse, allows a near endless variety of design choices. If you like MVC, MVVM, centralized state management, etc, you can build your app that way.
Enabling this level of flexibility is difficult, especially because we don’t know what sorts of things people might want to integrate into CanJS.
