The right decisions made for you.
Joosy claims to be conventions-centric. Concentrate on what you should do and not on how to achieve it. Incredible productivity out of box.
The dynamic rendering done right.
Bind your data to DOM without being limited to a specific template engine. Use HAML. Use helpers. And give it a sauce of identity map for a real joy.
Rails way to the browser.
Joosy inherits Rails' passion for conventions and happiness. It also inherits the typical solutions to the typical tasks. You are guaranteed to feel familiar and smile.
Don't wait for ECMA.
