Your complaint is vacuous at best and trolling at worst. You give no indication of what kind of errors you encountered, and it doesn't seem like you really look

Your complaint is vacuous at best and trolling at worst. You give no indication of what kind of errors you encountered, and it doesn't seem like you really looked into the problems you did have. There are some very valid criticisms of CoffeeScript, but you've raised none of those nor brought new ones.
