CoffeeScript vs JavaScript: What are the differences?

Developers describe CoffeeScript as "Unfancy JavaScript". CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. On the other hand, JavaScript is detailed as "Lightweight, interpreted, object-oriented language with first-class functions". 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.

CoffeeScript and JavaScript belong to "Languages" category of the tech stack.

"Easy to read", "Faster to write" and "Syntactic sugar" are the key factors why developers consider CoffeeScript; whereas "Can be used on frontend/backend", "It's everywhere" and "Lots of great frameworks" are the primary reasons why JavaScript is favored.

CoffeeScript is an open source tool with 15.2K GitHub stars and 1.99K GitHub forks. Here's a link to CoffeeScript's open source repository on GitHub.

Airbnb, Instagram, and ebay are some of the popular companies that use JavaScript, whereas CoffeeScript is used by Code School, Zaarly, and thoughtbot. JavaScript has a broader approval, being mentioned in 5080 company stacks & 6471 developers stacks; compared to CoffeeScript, which is listed in 364 company stacks and 170 developer stacks.

What are some alternatives to CoffeeScript and JavaScript?
TypeScript
TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.
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.

Stitch’s frontend is used to configure data sources and destinations and monitor the status of each. Although we have been using AngularJS since its early days, we recently introduced React components into our front end, which many of our developers find easier to work with. We started using CoffeeScript when it was one of the few options for a more expressive alternative to vanilla JavaScript, but today we opt to instead write new code in ES6, which we feel is a more mature alternative.

We chose TypeScript at Codecov when undergoing a recent rewrite of a legacy front end. Our previous front end was a mishmash of vanilla JavaScript and CoffeeScript , and was expanded upon haphazardly as the need arose. Without a unifying set of paradigms and patterns, the CoffeeScript and JavaScript setup was proving hard to maintain and expand upon by an engineering team. During a move to Vue.js , we decided to also make the move to TypeScript. Integrating TypeScript and Vue.js is fairly well understood at this point, so the setup wasn't all that difficult, and we felt that the benefits of incorporating TypeScript would outweigh the required time to set it up and get our engineering team up to speed.

Choosing to add TypeScript has given us one more layer to rely on to help enforce code quality, good standards, and best practices within our engineering organization. One of the biggest benefits for us as an engineering team has been how well our IDEs and editors (e.g., Visual Studio Code ) integrate with and understand TypeScript . This allows developers to catch many more errors at development time instead of relying on run time. The end result is safer (from a type perspective) code and a more efficient coding experience that helps to catch and remove errors with less developer effort.

Node.js is my choice because it uses very few resources to run and it is capable to handle tons of connections simultaneously. Most developers already know JavaScript, the evolution of ECMAScript is immediately reflected to Node.js and all you have to do is update your Server's Node.js version without time and effort. Thousands of improvements that makes it very powerful especially in asynchronous programming. The web is full of courses, dev communities, free sample code, plunkers and many knowledge sources on Node.js that facilitates the learning curve. What else we can ask from a legendary language that is still evolving? I am learning Node.js by developing a simple REST WebAPI and using it as a playground to test situations in which the main objective is to challenge Node.js and compare results and performance with .NET implementations and certain well known fast PHP implementations. Until now the results are astonishing. Summarizing: Node.js for backend is so far (in my opinion) the most recommended solution to get positive achievements in size, speed, power, concurrency, scalability, deployment and running costs.

Oof. I have truly hated JavaScript for a long time. Like, for over twenty years now. Like, since the Clinton administration. It's always been a nightmare to deal with all of the aspects of that silly language.

But wowza, things have changed. Tooling is just way, way better. I'm primarily web-oriented, and using React and Apollo together the past few years really opened my eyes to building rich apps. And I deeply apologize for using the phrase rich apps; I don't think I've ever said such Enterprisey words before.

But yeah, things are different now. I still love Rails, and still use it for a lot of apps I build. But it's that silly rich apps phrase that's the problem. Users have way more comprehensive expectations than they did even five years ago, and the JS community does a good job at building tools and tech that tackle the problems of making heavy, complicated UI and frontend work.

Obviously there's a lot of things happening here, so just saying "JavaScript isn't terrible" might encompass a huge amount of libraries and frameworks. But if you're like me, yeah, give things another shot- I'm somehow not hating on JavaScript anymore and... gulp... I kinda love it.

#ECMA

Long ago when Angular 2 evolved I had to decide between the new #Angular and TypeScript or React. I really love typing my code, but forced to use TypeScript was a bit too much. I prefer the new #ECMA standard and the evolution of the old and reliable JavaScript. So finding Flow (JS) was an incredible milestone in my career as a developer. Finally, I could use types in my code, and JavaScript with the new standard. I already had the experience of CoffeeScript, so TypeScript was not an option.

Slack

We have added very little to the CoffeeScript Hubot application – just enough to allow it to talk to our Hubot workers. The Hubot workers implement our operational management functionality and expose it to Hubot so we can get chat integration for free. We’ve also tailored the authentication and authorization code of Hubot to meet the needs of roles within our team.

For larger tasks, we’ve got an internal #CLI written in Go that talks to the same #API as Hubot, giving access to the same functionality we have in Slack, with the addition of scripting, piping, and all of our favorite #Unix tools. When the Hubot worker recognizes the CLI is in use, it logs the commands to Slack to maintain visibility of operational changes.

From a StackShare community member: "We are looking to rewrite our outdated front-end with TypeScript. Right now we have a mix of CoffeeScript and vanilla JavaScript. I have read that adopting TypeScript can help enforce better code quality, and best practices. I also heard good things about Flow (JS). Which one would you recommend and why?"

I love Python and JavaScript . You can do the same JavaScript async operations in Python by using asyncio. This is particularly useful when you need to do socket programming in Python. With streaming sockets, data can be sent or received at any time. In case your Python program is in the middle of executing some code, other threads can handle the new socket data. Libraries like asyncio implement multiple threads, so your Python program can work in an asynchronous fashion. PubNub makes bi-directional data streaming between devices even easier.
