Text{type:'text', content: string}

Any lines that don't fit into other formats, will be Text. content is the raw text to render.

render([Block]) => html

This module uses escape-goat to avoid HTML and JS injection to combat XSS.

Regular Text will be converted to <p> tags, however blank lines will be converted to <br/> elements as per the spec.

Preformatted text will be turned into <pre> tags. If there was an alt specified, the text will be wrapped in <code class="language-${alt}> so that it can be easily integrated with highlight.js.

List are converted to <ul> elements with <li> for each item in the list.

Paragraphs are converted to the appropriate <h1...n> elements.

Quote items will be wrapped in <blockquote> elements.
