JavaScript - client side or both client & sever side

[Avenger625]

I'm just a newbie...my question may seem very kiddish....I had an argument over this topic with my friends.....

Is JavaScript only a client side programming language or is it both a server and client side scripting language???

It's both, while still predominantly a client-side language, it can be used as a server-side language as well.

Javascript has been a very versatile language for a long time. With the recent rise in popularity of Node.js it has become much more popular to use on the server as well. It was possible to do this before Node.JS (and Common.JS) were around as well though, and even command-line applications can be written in JavaScript.
