Difference Between C# vs Js
C# is the elegant and type-safe object-oriented language that allows a developer to build a robust and very secure application that runs on the Net framework. Using C#, we can create Windows client applications, XML Web services, distributed components, and Client-server applications. It provides a very advanced code editor, which makes code editing very convenient and user-friendly, while JavaScript is the scripting language that makes the webpage interactive. Client-side programming means the code will run in the user’s web browser without the web server’s resources. It is used to perform dynamic tasks like quizzes and polls.

What is C#?
C# is a multi-paradigm programming language with highly expressive syntax. It was developed and designed by Microsoft Corporation. Its syntax contains curly braces, similar to C, C++, and Java. The application, which is built using c#, will run on the .Net framework. This language has rectified many complexities of C++ and provides many advanced features like null value types, enumerations, delegates, lambda expressions, and direct memory access.
The main advantages of C# languages are given below:
- Language-Integrated Query (LINQ) expressions make the strongly-typed query a first-class language construct.
- It supports encapsulation, inheritance, and polymorphism because it’s an object-oriented language.
- It supports inline XML documentation comments.
- It is statically typed.
- It has an operator and conversion overloading.
What is Js?
JavaScript is one of the most popular and widely used programming languages worldwide. It’s growing faster than any other programming language. Big companies like Netflix, Walmart, and PayPal are building internal applications.
You can work as a full-stack, front-end, and back-end developer.
What can you do with it?
For a long time, JavaScript was used only in a browser to build interactive web pages; after huge investment from the community and investment of large companies like Facebook, Google you can make:
- Full-grown web page and mobile apps.
- Real-time networking apps like Chats and video streaming services.
- Command-line tools.
- Development of the games.
Where does the JavaScript code run?
JavaScript was initially designed only to run on a browser; every browser has a JavaScript engine that can run JavaScript’s code.
JavaScript’s engine in common browser:
Firefox – Spider monkey
Chrome- v8
In 2009, engineers took an open-source Java engine in Chrome and embedded it in a C++ program; they called that program Node. Node is a C++ program that includes the Google V8 JavaScript Engine. Now, with this, we can run JavaScript code outside the Browser. Browser and Node provide the Runtime Environments for Javascript code.
Advantages of JavaScript:
- It’s an essential element of web development.
- UI/UX design, drop-down boxes, and search boxes can become interactive and competently set up with CSS and JavaScript.
- A server doesn’t take a load for web deployment.
- It’s comparatively more flexible in development time.
- It’s very popular with developers, so the resource for developing a project in JavaScript is easier to find.
- Learning JavaScript is much easier.
- Native Browser Support: Typescript code needs to be compiled, and the outcome in the JavaScript code.
- No need for Annotation in code.
- The code flexibility of JavaScript is excellent.
Head-to-Head Comparison Between C# vs Js (Infographics)
Below are the top 27 differences between C# vs Js:
Key Differences Between C# vs Js
Both C# and Js are popular choices in the market; let us discuss some of the significant differences between C# and Js:
- JavaScript is a prototype-based language, but c# is not.
- Javascript is a scripting language for web browsers. It also is known as New PHP, but C# doesn’t provide any feature like this.
- JavaScript is dynamically and weakly typed, but C# is statically and strongly.
- JavaScript’s primary programming paradigm is procedural, but C# primary programming paradigm is (class-based) object-oriented.
- Javascript doesn’t have an Integer datatype, but C# has an integer data type.
- Javascript doesn’t have array datatype, but C# supports array data type.
- In JavaScript, we use “function [function name],” and in C#, we use “void [function name]” or other function types.)
- C# runs the .NET framework, and it is best for making Desktop Applications while Javascript runs in a browser, so for making games and quiz other applications, JavaScript is better.
- C# is a compiled programming language. JavaScript is a scripting language. So, JavaScript can fail due to syntactic errors at runtime.
C# vs Js Comparison Table
The primary Comparison between C# vs Js is given below:
| Parameters | C# | JS |
| Designed by | Microsoft | Brendan Eich |
| Type | Type-safe object-oriented language | Object-oriented language |
| Static typing | Static | Dynamic |
| Platform | Limitation on platform | Cross-platform compatible |
| Lambda support | Supports lambda | It does not support lambda |
| Generic support | Great generic support | No generic support |
| LINQ (language-integrated query) | Supports LINQ | Doesn’t support |
| Garbage collection | Automatic garbage collection | Don’t have garbage collection |
| Platform | Amazing cross-platform support | Less cross-platform support |
| Consistency | Very consistent | Horrible |
| Flexibility | Very flexible | Less flexible |
| Frameworks | Supports .Net framework | Support various frameworks |
| Front-end/Back-end support | Supports front-end | Supports both |
| Versatile | Less versatile | Very versatile |
| Server-side scripting | No support for server-side scripting | Supports server-side scripting |
| Syntax | Concise syntax | Complex syntax |
| IDE | Visual Studio | Notepad, Notepad ++, Sublime |
| Operator overloading | Supports operator overloading | It doesn’t support operator overloading |
| Readability | Great readability | Less readable |
| OOPS concept | OOPS simplified with great syntax | Supports the OOPS concept |
| Complexity | More complex | Less complex in terms of understanding |
| Performance | High | Less |
| Resource | Hard to find a resource | Easy to find JavaScript developer |
| Closure script | It doesn’t support the closure script | Supports closure script |
| Over threading | JavaScript hides much of this with its call-and-response function structure. | C# gives the programming explicit control over threading |
| Integer data type | Supports integer data type | Doesn’t support |
| Array data type | Supports Array data type | Doesn’t support |
Conclusion
Based on the above comparison between C# vs Js, we can say C# is a strictly typed object-oriented programming language, and it’s used to develop console applications; Desktop applications and C# cannot run without the .NET framework, while JavaScript is a client-side scripting language used primarily for making interactive effects in web applications. It can execute in any web browser.
