Whatsapp Web uses Node.js?
I would like to know what technologies are used in the development of Whatsapp Web.
Ps: survey level question.

NodeJS is not used. In the backend, the server used is Yaws, which is developed in Erlang, one of the first languages completely aimed at competing applications.
On the front, there is no specific technology. Apparently, everything is developed in-house. Note only the use of Material Design, flex-box (when supported), ReactJS, Modernizr (to identify what the browser supports), MomentJS, VelocityJS in the animations.
About editors, etc, I believe that there is no specific. Facebook does not restrict your employees to a specific editor or IDE. Only the flow of tests and CI from them that is mandatory (remember that Facebook bought WhatsApp).
