Working with the DOM in JS frameworks

It's comfortable when at the frontend we can talk about the resulting DOM avoiding the not so favorite step of describing manually changing each HTML Element. It's comfortable when we describe the relationships between data and results. It's comfortable when all this inside is considered by itself.

Let's ask ourselves. How expensive it is? Have you ever rendered a list and caught yourself thinking that when scrolling everything started to slow down although the number of HTML elements is not very high?

During this session, we will reflect on the complexity of algorithms about how frameworks reconcile and update DOM elements.
