If you want to learn C# to write some backend code you can also check out Node.js which is basically JavaScript running outside the browser. You can create any kind of web servers, APIs, scrapers, automation scripts, etc using all the same JavaScript.

A good entry to Node is Express.js. It is the most common web framework for Node. It's well documented and there are a lot of educational materials for it.

C# is .net framework of a programming language specially different from the programming languages you're used to. If you learn C# you will be experienceed in coding with VIsual Basic .net and also creating web development using ASP and this ASP also include JavaScript function.... I urge you to learn it

I prefer functional programming because it produces less buggy code (thus I recommend F#), and is simply better to learn this paradigm earlier on in your coding career rather than later. It can also do most stuff C# can do, namely code with .NET core. If you're going to learn .NET then you should learn Node.js+Express first though before doing web development with C#/F#

I think you can manage to find something about this topic. it's pretty popular one. ex: https://www.educba.com/c-sharp-vs-js/

Something I don't see discussed enough over the internet is the performance difference. I don't think you should worry about this. 95% of the time you won't notice the difference on your day to day projets. You will know what you need in terms of performance when you get there.

In my opinion, a modern developer should have deep knowledge about Object Oriented (OOP) and Functional Programming (FP). The programming language is something that must come later. Any good programmer should be able to switch from one programming language to another easily, if they follow OOP and FP. There are languages, though, that must absolutely be in the portfolio of a modern developer: Java, C#, Python and JavaScript. But be prepared to know also Scala, Kotlin, Swift, Go, Ruby, Rust and TypeScript.

It depends on your preferred career path, if you want to work in start-up/scale-up environments, you probably want to go with a language like Django for the rapid development (fast to production). On the other hand, C# or Java would be better for building long term and large scaled applications, although, Django could certainly achieve this as well. I also want to second that it won't hurt to know both languages, pick your technologies wisely according to the use case, don't stick to a single technology stack. :)

C# and Python are both great languages. With great communities, libraries, frameworks, opportunities. I think it will be the same in a near future.

It’s matter of your likes, and your next jobs.

Dot net core is a little faster on performance. Python more popular with dynamic types. Probably the most lovable language.

It depends.

From times to times I asked or was asked that same question. Technology aside, it's important to consider the skills and expertise that the dev team has. Whether you use language A,B or C or framework X,Y and Z, if your team has a strong background and experience with something make it count too.

I would recommend Go simply because as you mentioned, it's super light. No need to bring in the whole .NET suite to get a simple REST API up and running. Even if your API is a bit complex, Go should be able to handle it.

I started out with C# and .NET and I loved it. In my opinion, it was the perfect way to start learning the fundamentals of software development however I always felt like I was at a disadvantage when I was doing .NET development. Granted, .NET Core is now open-source and cross-platform, but I moved to Node.js simply because it is incredibly popular. I never thought I'd learn to love JavaScript it the way I did with C#, but I learned to love it pretty quickly, especially once I started using TypeScript. You get all of the benefits of C# and JavaScript all in one. If you've built a REST API with Python/Flask/Django, you'll be able to learn Node.js/Express/TypeScript well enough to migrate your API very fast and it's incredibly easy to host for free on any number of services.

I'm new to Go, I've got very little experience but the 'feel' of Go, isn't like Python in my opinion. Go has a pretty steep learning curve, much steeper than C# in my opinion. So if you are willing to consider Node/Express/TypeScript, I think you may really like it. If you're picking between Go and C#, I'd go for C# as of today, but once I am more comfortable with Go (which I anticipate being a slow process) I may change my mind.

At this moment in time, in late 2020- Node/Express/TypeScript feels like the obvious choice to me as a former C# developer.

The best language for you is the one that you know best!

Its a bit of a guess, but from your question and the difficulties you have with Python it seems to me the problem you describe is the manifestation of a bad design/architecture/code quality. These are not the problems of a language itself!

The experience you gained over the past years with your current programming language will outmatch any benefits of another language that you start from zero.

Because in the end of the day languages aren't all that different when it comes to fullfil the same task, it's more the tools, framework and ecosystem for a particular problem that make a difference.

I worked with Java, C#, Go and recently in Phyton, and I would choose Phyton over Go for WebApps, even I like compiled languages more. Go is a very simple language, I would even say maybe too simple. I can't stand all those go boilerplate if err checks, the broken filesystem, the date/time mess and many more things that aren't actually relevant for business application at all. Go has its advantages but not for WebApps.

Keep the lang and improve your skills and architecture you will benifit more from it than from a new language.

I recommend Go for backend. It's younger than C# doesn't mean it's not mature. It's already mature enough to be run on production. You can see there are already many companies in the world adopting Go as their backend business logic or tooling. I can name a few like Github, Shopify, uber, twitch, and many more. It's easier learning curve, low entry barrier, better performance than C#, better memory consumption than C#, since there's no VM/runtime needed. It's suitable for large scale system and large codebase for readibility and long maintainability. It's simpler than C# since no class, inheritance(this can cause hard to maintain software), exception, etc. You can still implement OO way in Go without those feature. Simple file structure, only main files and package files. It compiles to single binary and easy to deploy and work around it, unlike C# who compiled to IL and you need to wrap all those IL files to be run inside separated web server(even .Net/.Net Core platform provide built-in web server). For libs, don't worry, there are many open source libs you will found on Github and already adopted by many companies. Go is employed in personal, startup, even corporate level.

I suggest Go because it has a simple and clean ecosystem. The language is simple. You don’t need complex configs or installs either. You’ll be up and running very quickly. It doesn’t have as much as .NET but its standard library is more than sufficient for RESTful APIs. Concurrency is much, much easier too.

C# I’d definitely recommend later on. The .NET framework, especially core, is extremely powerful and there’s little you can’t build with it. Go won’t take you long to be productive with.

I have some systems on production using both languages. I tend to use golang if the API is small or medium size, but if I am going to build a large system definitively I use c#(asp netcore).

I would recommend C#, particularly Simplify.Web web-framework. C# is easy to start with (especially .NET Core). Simplify.Web is also easy to start with, no extra setup required for simple API, but on the other hand you have power of C# and full control over your API with ability to extend.

If you want to stick with python you may want to consider Fastapi. It uses Pydantic to give you strongly typed models and validation. It generates openapi docs for you out of the box. They have good documentation as well and they claim it is really fast.

The database your are going to connect and the needed libraries could decide. Because both are awesome languages.

I use TypeScript because:

• incredible developer tooling and community support
• actively developed and supported by Microsoft (yes, I like Microsoft) ;)
• easier to make sense of a TS codebase because the annotations provide so much more context than plain JS
• refactors become easier (VSCode has superb support for TS)

I've switched back and forth between TS and Flow and decided a year ago to abandon Flow completely in favor of TS. I don't want to bash Flow, however, my main grievances are very poor tooling (editor integration leaves much to be desired), a slower release cycle, and subpar docs and community support.

I use TypeScript because it isn't just about validating the types I'm expecting to receive though that is a huge part of it too. Flow (JS) seems to be a type system only. TypeScript also allows you to use the latest features of JavaScript while also providing the type checking. To be fair to Flow (JS), I have not used it, but likely wouldn't have due to the additional features I get from TypeScript.

We originally (in 2017) started rewriting our platform from JavaScript to Flow (JS) but found the library support for Flow was lacking. After switching gears to TypeScript we've never looked back. At this point we're finding that frontend and backend libraries are supporting TypeScript out of the box and where the support is missing that the commuity is typically got a solution in hand.

I use TypeScript because the tooling is more mature (the decision to discontinue TSLint in favor of moving all its checks to ESLint is a thoughtful and mature decision), there's a ton of examples and tutorials for it, and it just generally seems to be where the industry is headed. Flow (JS) is a fine tool, but it just hasn't seen the uptake that TS has, and as a result is lacking a lot of the nicer small things, like thorough Visual Studio Code integration, offered by TS.

We currently use TypeScript at work. Previously we used Flow (JS) but it was sometimes really difficult to make the types work the way you want. Especially non-trivial types were problematic. And the IDE support wasn't good, Flow took too much resources and sometimes remain stuck and do not show errors (I use Visual Studio Code). With TypeScript we almost do not have these problems. IDE support is superb, working with types is much easier and typing system seems more mature and powerful. There are some downsides (like partion inheritance etc.), but TS team is still pushing it forward. So for me TypeScript is clear winner.

We use Underscore because it's a reasonable library for providing all the reasonable helper functions missing from JavaScript ES5 (or that perform poorly if you use the default ES5 version).

Since we're migrating the codebase to TypeScript , we'll likely end up removing most usage of it and ultimately no longer needing it, but we've been very happy with the library.

I use TypeScript because it's adoption by many developers, it's supported by many companies, and it's growth. AngularJS, React, @ASP.NET Core. I started using it in .NET Core, then for a job. Later I added more Angular experience and wrote more React software. It makes your code easier to understand and read... which means it makes other people's code easier to understand and read.

I use TypeScript for Web Applications and for both frontend and backend because it has a lot of tooling around it and they really got the types and type safety right. Flow (JS) on the other hand lacks tooling and most of the times I scramble to find the right way of building my contracts in which TypeScript is very intuitive and natural. Additionally TypeScript is very similar to Java so your backend engineers and full stack engineers can work with it without much of context switch.

The only time I think Flow shines is (based on probably my outdated knowledge) Flow is/was the only option if you want/wanted to build a React Native application mainly because React Native transpiler at the time I was working with it would only work with flow.

I use TypeScript because I tried both on a Meteor project, and found the quantity of errors it enabled us to catch and the simplification of code it allowed was higher than Flow (JS).

If you will start a project from scratch I recommend to use TypeScript. But, If you work with legacy projects written in JavaScript I recommend Flow (JS). Both tools have the same objective: reduce the bad code (which create illegible code, generate bugs e problems to maintenance). Flex helps you to avoid fall in bad codes, but TypeScript prevent you to c you to create bad codes. I believe cause this some JavaScript fans don't like TS, because TS block you to write some types o code. This is the fundamental difference between TS and Flow: Flow avoid problems, but no force. TS force you to prevent problems.

I use TypeScript because it's the most mature/issue-free Javascript type-checker available, as far as I've seen.

I use TypeScript because of broad support, on tools, repos, community ... the only reason to consider flow is if you're a facebook employee

I recommend TypeScript. When used correctly, TypeScript can enable your application to be scalable, easy to refactor, safe, and stable. One of the biggest draws of working with any typed language is that it forces you to think about your functions' inputs and outputs. This is invaluable as it can lead to more declarative, functional style code that ultimately can be easier to reason about.

TypeScript is however not a silver bullet. Just like anything new it takes time to fully understand the concepts of types, interfaces, abstract classes, and enums. In my experience engineers who excel when using TypeScript are those who have experience working with a statically typed language.

I use TypeScript because i love to program in Angular and used in node as well
