Maybe the problem lies in your brain, and not coffee script. You aren't a super genius. Humble yourself, admit you suck ass, and try to make yourself better

Presumably you have sources to back up this incredible sounding statement.

It's not really an "incredible sounding statement", it's just logic. What makes a program more bug prone is the amount of logic there is in it. If it takes you 1000 lines of code in language X and it takes you 500 lines of code in language Y to write the exact same thing, you still have the same amount of logic in both language. The only difference will be the density of the code. Changing the density of the code doesn't change the fact that it will have the same amount of potential bug in it.

Beautifully said, truly. The problem isn't the language, it's the program.
