Differences Between JavaScript vs C#
JavaScript is a high-level programming language. It is mostly used in web browsers. Along with HTML and CSS, JavaScript is the foundation of the world wide web. It makes the interaction between client and server possible. A vast majority of websites uses JavaScript and almost all modern web browsers have a JavaScript engine.
JavaScript supports event-driven, functional and imperative programming styles, it is a multi-paradigm language. It can work with text, arrays, regular expressions, dates and can perform basic manipulation of document object model (DOM).
C# is a general-purpose, object-oriented programming language. It is intended for a simple, modern and general-purpose language. It has been designed to build software ranging from small functions to large operating systems. It is also a multi-paradigm language which is strong typed, imperative, declarative, functional and component oriented.
In this JavaScript vs C# article, we shall compare the essential features of both JavaScript and C#, understand their uses, know their advantages and disadvantages and also highlight a key difference between JavaScript and C#.
After going through the content, it is expected that the reader would be able to make an intelligent decision to choose between JavaScript vs C# for a given task.

- JavaScript has so many tutorials, documents, and help available that it is easy to learn.
- C# is so complex and vast, it may frighten the learn in first sight.
- The developer community and peer network for both JavaScript vs C# language are strong but in a hindsight, it seems C# has a better peer group among windows developers.
- Nowadays, as nobody can get away with learning just a single language, it does not matter which one you start with. Having the knowledge of both JavaScript vs C# will only be beneficial in long run.
- Generally, one needs to write so many lines of code in C# like Java to get things done which is not the case in JavaScript.
- Language syntax of C# is more consistent than plain JavaScript.
- One good thing about JavaScript is that it is still evolving, newer things build in other languages also started coming into JavaScript.
- Now that TypeScript is evolving, it is worth learning. TypeScript bring many missing key features to JavaScript which was not there in vanilla implementation.
- JavaScript has thousands of free libraries available and strong community support while C# is very limited as it is primarily windows based.
Comparison Table JavaScript vs C#
In this section, we shall do a key comparison of JavaScript vs C# features.
| JavaScript | C# |
| JavaScript runs in most browsers without any plugin requirement. | C# needs a plugin like a Silver light. |
| It cannot read or write files in client machine | It can read and write files if given Silver light version allows for it. |
| JavaScript is dynamically typed. | C# is statically typed. |
| JavaScript is weakly typed. | C# is strongly typed. |
| JavaScript has separate libraries to do native querying like underscore.js | C# has LINQ, a powerful .NET component using which native querying can be done. |
| JavaScript does not have an operator and conversion overloading. | C# has operator and conversion overloading capabilities. |
| It was developed by a small team at Netscape | It was developed at Microsoft |
| The main purpose of JavaScript is to make interactive web applications. | C# can be used in so many widely different applications. |
| JavaScript’s scope is limited and there are several pitfalls to this language. | C# is a really robust language which developer prefer across the globe. |
Interesting pros and constable for JavaScript and C# can make the comparison even better.
JavaScript
| Pros | Cons |
| No installation is required to run JavaScript. | Many errors may pass silently |
| It is a must for web development. | You may easily use globals and don’t realize it. |
| It can run on both server and client side. | Wired type coercion is everywhere |
| It has great functions and comes up with lexical closure. | It is complex |
| It has a massive ecosystem and application building is easy. | Each browser may behave differently for the same code |
| It has a C like a syntax and debugging is easy. | It has limited standard libraries |
| It is a prototype based object oriented system. | Asynchronous coding is difficult at least for beginners. |
| JavaScript developers are in high demand. | Counter-intuitive type conversions |
C#
| Pros | Cons |
| It has a great IDE for windows. | It has a complex syntax. |
| It is an incredibly designed language. | It depends on IDE to do coding. |
| One of the most used OO language. | It lacks standard library support for an immutable data structure. |
| Best to design windows, highly in demand. | Expensive to use meaning products build using C# generally tends to cost higher. |
| Can be used to design unity games. | |
| Truly universal | |
| Can be used as a mix of high and low-level language. | |
| It supports many platforms. |
Conclusion – JavaScript vs C#
To summarise the above discussion, one can have a quick look at the bullet points below to wisely learn the difference between JavaScript and C#.
- If the purpose is client-side programming via a web browser, go for JavaScript. Better use HTML5 and TypeScript (advanced version of JavaScript).
- On the Desktop development, use C#.
- On the server development, use TypeScript and NodeJS.
TypeScript is like C# only and is backed by Microsoft. TypeScript compiles to JavaScript.
With the above comparison and explanation, you must have got a good idea of both JavaScript vs C# language and the functionality that each provides. Both the languages are in high demands and each serves a very important purpose and probably so it is difficult to point out which is good and which is bad. For somebody who is breaking into the world of programming and development, it is important that he/she should learn both. However, a general inclination among developers is towards C#. There are so many benefits that it provides which overshadows JavaScript. A general suggestion could be to focus more on C# and make it the primary language and keep JavaScript knowledge as a need-based skill.
