      What are some alternatives to CoffeeScript, Flow (JS), and TypeScript?
      JavaScript
      JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
      ES6
      Goals for ECMAScript 2015 include providing better support for large applications, library creation, and for use of ECMAScript as a compilation target for other languages. Some of its major enhancements include modules, class declarations, lexical block scoping, iterators and generators, promises for asynchronous programming, destructuring patterns, and proper tail calls.
      Babel
      Babel will turn your ES6+ code into ES5 friendly code, so you can start using it right now without waiting for browser support.
      jQuery
      jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.
      Python
      Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
