Question

JavaScript

Can data (photos, passwords, logins, etc.) be loaded from the browser's javascript code into the couchdb database? Or does everything have to happen on a Node.js based server? How is it usually implemented in social networks (who knows)? Interested in a bunch of javascript and couchdb.

Answer 1

JS is designed to work with front-end (client-side). Data processing should be carried out by server languages. As for the social networks - AJAX.
