What are the weapons I'm hearing about?

Question

I keep seeing "weapon" coming up. Does this have to do with challenges?

Answer 1

Yea. C# was added :))

Answer 2

Yes, it does. A weapon is the programming language you are challenging the other person in.
For example, if you choose Python as your "weapon", then you and your opponent will only be asked Python-related questions.
Get it?

Answer 3

Yes, thankyou. I was challenged in java which I don't know, and still managed to beat the opponent
