Why we need Nodejs before setup Phonegap?

I came across the site of Phonegap and in site they told us to install nodejs before setup Phonegap I actually can't understand why we need nodejs installed before starting Phonegap?

Answer 1

You can use .Net as Backend for Phonegap application, you do Not "run" using .Net.

Have a look at Phonegap FAQ

A PhoneGap application may only use HTML, CSS, and JavaScript. However, you can make use of network protocols (XmlHTTPRequest, Web Sockets, etc) to easily communicate with backend services written in any language. This allows your PhoneGap app to remotely access existing business processes while the device is connected to the Internet.
