"Java/Python/etc is too slow." Then don't use it when speed is an issue! "C/C++ are unsafe." Only if you don't know how to manage memory & don't leverage tools. "javascript doesn't need classes." It's the native language of the web, it better damn well cater to the preferences of the significant propertion of programmers who HAVE to use it. Generally: "Language X is bad because reason Y." No it isn't. You're using it wrong!
