Astro is a new web framework that is very different from the others.

It's not a replacement of React, Angular or VueJs because it allows to build fast web sites focused on content using a new concept called island.
An island, by default, is a static template with no javascript so it loads very quickly but it can also be an interactive UI built with React, Svelte, Vue or most of the modern front-end frameworks.

Astro supports several other interesting features but in this video I wanna show you how you can mix several frameworks onto the same page.
