What are panics in programming?
I've only seen them within the context of Go and Rust (looking up the results of a similar query on DuckDuckGo, which gave a dissatisfying yield).

Are they just a thing Go made up, and Rust got inspired by?
Are they just a synonym for "Runtime Error"?
Are they a new kind of R.E.?

Please, tell me, what differs a panic from a R.E., when were panics first introduced to the programming scene, and why does it seem so few languages have them?
