What are the differences between paged.js and paged.polyfill.js?
Paged.js comes as two different scripts
paged.js: this version of the script let the user define the content, the styles and the output element of paged.js, as explained in Paged.js readme. It follows those rules:
let paged = new Previewer();
let flow = paged.preview(DOMContent, ["path/to/css/file.css"], document.body).then((flow) => {
console.log("Rendered", flow.total, "pages.");
})paged.polyfill.js: this version of the script is the default setup for paged.js: it will start as soon as the page is loaded, it will use the full content of the webpage, and all the styles linked to the content, and the output will be rendered as the replacement of the fullbodyelement of the webpage.
Paged.js will work the same way with both scripts, the first one allows for more customized uses.
