C# vs ES6: What are the differences?

What is C#? Simple, general-purpose, object-oriented programming language for the .NET platform. C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

What is ES6? The next version of JavaScript. 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.

C# and ES6 belong to "Languages" category of the tech stack.

"Cool syntax" is the top reason why over 280 developers like C#, while over 98 developers mention "ES6 code is shorter than traditional JS" as the leading cause for choosing ES6.

Slack, StackShare, and HubSpot are some of the popular companies that use ES6, whereas C# is used by Stack Exchange, PedidosYa, and Coderus. ES6 has a broader approval, being mentioned in 1440 company stacks & 1658 developers stacks; compared to C#, which is listed in 684 company stacks and 1118 developer stacks.

    PHP
    Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
    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.
    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.
    Java
    Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
    HTML5
    HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

    I've used .NET for many years, but only in recent years, after Microsoft introduced .NET Core, I've found a new love and excitement for the technology again. The main driver for us using .NET Core is not that it is cross platform compatible, open source or blazingly fast (which it is!), but the fact that we can use (what we consider) the best programming languages (mainly F# and C#) to carry out our jobs without sacrificing the other benefits.

    Today we run most of our web infrastructure on .NET Core in Docker containers, deployed into a Kubernetes cluster which spans across multiple time zones in the Google Cloud and we couldn't be happier. Due to the portability of the .NET Core platform we are even able to develop many new services as serverless functions with F# which has become an absolute game changer.

    How Uber developed the open source, end-to-end distributed tracing Jaeger , now a CNCF project:

    Distributed tracing is quickly becoming a must-have component in the tools that organizations use to monitor their complex, microservice-based architectures. At Uber, our open source distributed tracing system Jaeger saw large-scale internal adoption throughout 2016, integrated into hundreds of microservices and now recording thousands of traces every second.

    Here is the story of how we got here, from investigating off-the-shelf solutions like Zipkin, to why we switched from pull to push architecture, and how distributed tracing will continue to evolve:

    We are always building new features and replacing old code at StackShare. Lately we have been building out new features for the frontend, and removing a lot of old jQuery code (sorry jQuery but it's time to go).

    We've mainly been using React, ES6 and JavaScript on the frontend to build out the components, and we've been slowly removing some legacy MobX and using GraphQL and Apollo for our state management, if we need to control state further than GraphQL and Apollo allows us to we use just plain React with #context , or the new fancy React #hooks🎣 .

    As we've moved towards the above tech, its really made smashing out new features and updating legacy code super fast, and really fun!

    We use JavaScript because it's the standard for web development, especially with browser execution. And, over the years, some smart work by the W3C has taken Javascript from the most-hated-language to the okay-I-can-make-that-good. No small feat!

    Obviously, using ES6 and TypeScript is what makes it decent in browser contexts. Throw in a bit of React and now we're cooking with gas!

    I use C# because it is incredibly clear and easy to use. The documentation is second to none, being a Microsoft product, and if you just want something that works without exploring a million frameworks and libraries you can pretty much start a C# website and have it running in an hour. C# is basically, in my opinion, a cleaner and easier to use Java. My experience is limited to web design, however. It might come down to personal opinion but I wouldn't even know where to start writing a java back end website but visual studio makes it very easy to write it in C#. If you are new to full stack development I can't recommend Visual Studio enough. It does, however, hide away a lot of abstraction that programmers much more clever than me use to make really interesting websites and server setups. C# will do everything you need to create any website you can imagine, though.

    Before I end my rant about how much I love this language I'd like to reiterate how easy it is to figure out problems you encounter. I was stuck on how to store a path string in a database and found the solution by browsing the documentation for 2 minutes, which included examples. Every ASP element is clearly and wonderfully documented.

    I have always been interested in building a real-time multiplayer game engine that could be massively scalable, and recently I decided to start working on a MMO version of the classic "snake" game. I wanted the entire #Stack to be based on ES6 JavaScript so for the #Backend I chose to use FeathersJS with MongoDB for game/user data storage, Redis for distributed mutex and pub/sub, and Socket.IO for real-time communication. For the #Frontend I used React with Redux.js, the FeathersJS client as well as HTML5 canvas to render the view.

This API provides a way to add and manage more complex permission structures than can easily be maintained in Azure AD.

    Gatsby has been at the core of our Shop system since day one. It gives its User the power to create fast and performant sites out-of-the-box. You barely have to do anything to get great Lighthouse results. And it all runs on ES6 JavaScript.

    The power of SSR React and then hydrating it client-side to add interactivity and App-like feel is what makes Gatsby powerful.

    It comes with a ton of plugins, that are mind-boggling: Image Processing, GraphQL, Node.js, and so much more. This is thanks to a great ecosystem, a great user-base and the revolutionary Community work, which led to the Gatsby repo to be one of the most committed to, out there.

    Application and Data: Since my personal website ( https://alisoueidan.com ) is a SPA I've chosen to use Vue.js, as a framework to create it. After a short skeptical phase I immediately felt in love with the single file component concept! I also used vuex for state management, which makes working with several components, which are communicating with each other even more fun and convenient to use. Of course, using Vue requires using JavaScript as well, since it is the basis of it.

    For markup and style, I used Pug and Sass, since they’re the perfect match to me. I love the clean and strict syntax of both of them and even more that their structure is almost similar. Also, both of them come with an expanded functionality such as mixins, loops and so on related to their “siblings” (HTML and CSS). Both of them require nesting and prevent untidy code, which can be a huge advantage when working in teams. I used JSON to store data (since the data quantity on my website is moderate) – JSON works also good in combo with Pug, using for loops, based on the JSON Objects for example.

    To send my contact form I used PHP, since sending emails using PHP is still relatively convenient, simple and easy done.

    DevOps: Of course, I used Git to do my version management (which I even do in smaller projects like my website just have an additional backup of my code). On top of that I used GitHub since it now supports private repository for free accounts (which I am using for my own). I use Babel to use ES6 functionality such as arrow functions and so on, and still don’t losing cross browser compatibility.

    Side note: I used npm for package management. 🎉

    *Business Tools: * I use Asana to organize my project. This is a big advantage to me, even if I work alone, since “private” projects can get interrupted for some time. By using Asana I still know (even after month of not touching a project) what I’ve done, on which task I was at last working on and what still is to do. Working in Teams (for enterprise I’d take on Jira instead) of course Asana is a Tool which I really love to use as well. All the graphics on my website are SVG which I have created with Adobe Illustrator and adjusted within the SVG code or by using JavaScript or CSS (SASS).

    I use C# because of the ease of designing user interfaces compared to Java. Using Visual Studio makes C# a breeze for prototyping and creating apps and I really appreciate how quickly I can turn an idea into reality. I was first introduced to C# in a special topics course and quickly started preferring it over Java. The similarities between the two made the switch easy while the added benefits C# offers made it very worth it.

    Arbor Health, LLC uses C#C#

    C# is the most productive production language - it exposes a lot of functional conveniences along with the robustness of strong typing. And they're finally embracing the open source community - a huge plus.

    #Language Features We use the basic syntax (for, foreach, if,while) and object oriented constructs (classes, very simple inheritance).

    We also use lambdas and block methods extensively, an intermediate level programming construct, but in a very formulaic and predictable way.

    Kurzor, s.r.o. uses ES6ES6

    We started using CoffeeScript years ago, so the switch to ES6 is quite natural in our team. ES6 of course advances the JS standard to a level of an advanced language. We are using it today simply because it: 1. helps to keep the code shorter, 2. integrates easily with JSX, 3. helps to deal with immutable using const.

    ES6 is a new-ish, modern form of JavaScript that adds in extra functionality that make code cleaner and easier to work with, such as arrow functions, const and let declarations, array helper methods, object/array destructuring etc.
