Here's how I would describe Vue…

Defining a UI Component

Option 1: JavaScript inline strings

Defining a UI Component

Option 2: <script type="text/x-template">

In an HTML file far, far away…

Defining a UI Component

Option 3: Single-file .vue components

Defining a UI Component

Option 4: Multi-file .vue components

Defining a UI Component

Option 5: Multiple languages

Defining a UI Component

Option 6: JSX

Registering a UI Component

Option 1: Local registration Option 2: Global registration

Async!

Marko is fast(higher is better)

Why is Marko Fast?

HTML streaming for the server

Writable async stream

Compiled

VDOM rendering for the browser

Async VDOM tree builder

Compiled

Static sub-tree optimization

Created once

Reused for every render

Compiled

Server-side rendering(with seamless isomorphism!)

Server Browser

HTML + { state, input, globals }
