Reactivity

Introducing Reactivity
00:02:51 - 00:08:27
Introducing Reactivity
After clarifying the term reactivity in the context of working in Vue.js as changing the state and how the state reflects the update the DOM system, Evan walks through a simple example of how Vue.js's rendering system works.
Challenge 1: Getters and Setters
00:08:28 - 00:13:39

Challenge 1: Solution
00:13:40 - 00:23:49

Render Functions

Introducing Render Functions
00:41:39 - 00:44:50
Introducing Render Functions
Evan illustrates how Render Functions help in the process of managing state by tracking changes from DOM and virtual DOM.
Virtual DOM
00:44:51 - 00:50:41
Virtual DOM
Evan reviews virtual DOM, which is a lightweight representation of what actual DOM should like at a given point in time. Virtual decouples rendering logic from actual DOM allowing rendering capabilities in non-browser environments such as server-side and native mobile rendering. - _https://vue-template-explorer.now.sh/
Putting Everything Together

Render Function API
00:55:33 - 01:03:16
Render Function API
Evan reviews the Render Function API by examining a component with an "h" function. The "h" function is a convention based on hyperscript, a method for writing HTML through JavaScript. Evan takes questions from students. - - _https://github.com/hyperhype/hyperscript - _https://vuejs.org/v2/guide/render-function.html#The-Data-Object-In-Depth
