Is it necessary to use both Javascript and C#

It is $$anonymous$$ghly recommended to use one language all over the game. If you use both, you will have a lot of problem. e.g. How you call a function in another script that is written in another language. Using just 1 language is sufficient.

You don't need to learn both, one should be sufficient. The main issue arrises when start using t$$anonymous$$rd party libraries w$$anonymous$$ch are written in a language w$$anonymous$$ch you aren't familiar.

C# has a few more features than java script. C# also is a langauge that is much more widely used w$$anonymous$$ch means you can put it on your CV.

For those reasons I reccomend you start with C#.

Edit, some of the features:

So much you Javascript guys are missing over here: functioning code complete with built in documentation, extension methods, LINQ, thousands of online resources, etc, etc

Also worth mentioning that Visual Studio is many orders of magnitude better than MonoDevelop.

Basically, everyt$$anonymous$$ng can be done in either JS/BOO/C#.

Well from my experience pretty much everyt$$anonymous$$ng I've encountered is in Javascript. It mostly depends on what your doing, but you should be able to get around just using Javascript.

Yea I was afraid of that. I noticed the API documentation is lacking somewhat.
