Newb Questions Intro and Coding

Hey everyone i have not started using unity yet but i know that it supports scripting in c# java script and boo i just want to know if this is necessary for most things or if it is more for specific problems and what you have all used it for i guess this might sound like a stupid question however with its GUI and how it implements things that i have seen it seems a lot of potential scripting is "done for you"

also to someone who has attempted to get network/internet play working if they can explain how hard it is i know this is relative however i have some experience with java script at least enough to read it and understand most and another in the group is a computer science graduate and worked in coding for 4 years

Unity provides a heck of a lot of power without needing scripts, but I can't imagine any interesting application which would not require some coding. It's not as bad as Torque or Multiverse or some of those others that are pretty much all code. The JScript (note, it's not really Javascript) is pretty easy to pick up, and the online docs and tutorials are excellent. If you are familiar with the basics of programming, you should have no trouble picking it up.
