Create a Hello World App with Preact

By creating a simple ‘hello world’ example application first in vanilla Javascript, and then in Preact without any tools, we’ll learn what type of problems Preact is solving for us and how is works at a low level. Then we’ll switch to a Webpack + Babel setup we’ll cover some fundamental concepts such as, which imports we need, how to create a component, how to use JSX and finally how to render our component into a target element in a web page.
