Implementing a modern UI framework is a very interesting challenge: it is quite difficult to provide

a robust set of APIs that is also performant. Many popular frameworks such as React or Vue chose

to use a virtual DOM as an underlying rendering method.

Odoo own framework, Owl, is also based on a virtual dom, but with an additional twist: instead of manipulating

the DOM element by element, it works with a much larger unit (the "block"). In this talk, we will explain what

a virtual DOM is, why it is useful, and how block virtual DOMs are the next evolutionary step in rendering

technologies.
