C# vs JavaScript: 26 Differences That No One Will Tell You

C# vs JavaScript

C# and JavaScript are two of the highly used programming languages in the world today. While C# is mainly used for developing Windows desktop applications, web applications, and games, JavaScript is mostly used for developing web applications, web APIs, and mobile applications. However, with the increasing popularity of technologies such as Node.js and React Native, JavaScript has also become a popular choice for developing desktop and mobile applications.

Both C# and JavaScript have their own pros and cons. Choosing the right one between them depends on the specific needs of the project at hand. In this blog, we’ll explore the differences between C# and JavaScript, their respective features, and what makes them unique. We’ll also dive into the pros and cons of each language and discuss scenarios in which one language might be a better choice than the other. So, let’s dive in and explore the world of C# and JavaScript!

Whether you’re looking for C# assignment help or JavaScript assignment help, this blog will provide a comprehensive guide to these two popular programming languages and help you choose the right one for your project.

C# vs JavaScript

Computers communicate in their own languages. While you may realize that a computer forms data in a progression of 0s and 1s that the human brain can’t keep up with. However, you may be amazed that binary is not the main language computers speak. Also, there are a number of or mainstream languages that can be utilized to communicate with computers that are free of the client’s own local language.

However, we’re discussing PC programming languages, and that implies you have to go over the differentiation of C# vs JavaScript. Such as, any programmer realizes that not all coding languages are made similarly or can even be utilized for a similar reason.

Generally, When we discuss the difference between C# and JavaScript, the contrasts between these two codes are huge. In any case, these two programming languages do have a couple of places where they overlap. Likewise, check out this blog for a detailed difference between C# vs JavaScript.

What is C#?

C# (we pronounce it as C sharp) is an object programming language that was developed by Microsoft in 2000.

In 2002, its first version (C# 1.0) with the  .Net framework was released.

.Net framework is like a machine that helps C# and other languages to compile and execute the programs.

Till now C# got many versions updates, the latest version of C# is 10.0 which was released recently in 2021.

Since it is derived from the C language, it is quite similar to it.

It is a type-safe programming language so it helps a lot in improving the security of the program.

C# language allocates that memory which the code has permission to execute, this is the main reason by which C# provides such good security.

For example:

C# Program

// hi you print in C#

public class hi 


public static void Main()


System.Console.WriteLine(“hello There!”);




Hello, There!

Features of C# programming language 

  • Easy-to-use Generics
  • Lambda Expressions and LINQ 
  • Events and Properties 
  • Conditional Compilation
  • Integration with Windows
  • Indexers
  • Assembly Versioning
  • Boolean Conditions
  • Simple Multithreading
  • Events Management and Delegates 
  • Automatic Garbage Collection
  • Standard Library

Advantages Of C#

The C# languages main advantages are given below:

  • C sharp is statically typed language.
  • Language-Integrated Query (LINQ) expressions create the strongly-typed query a first-class language construct.
  • C# has a conversion and operator overloading.
  • However, C sharp supports the concept of polymorphism, inheritance, encapsulation because it is an object-oriented language.
  • Also, it helps inline XML documentation comments.

Cons of C#

No one is perfect in this world, everyone has some type of cons in them, In the same way, apart from its advantages, C# also has some cons.

Here are some cons which you can find in C# -:

  • C# x-platform GUI is very poor.
  • C# language mostly depends on the .Net Framework, which makes it less flexible.
  • It does support multiple inheritance.
  • C# is strongly tied to the .NET framework, which makes it a Windows-centric language.

What is Javascript?

JavaScript is recognized as the most powerful Coding language on the web. It is originally utilized to develop network-oriented applications. Furthermore, it is most usually utilized for web pages, whose implementations support client-side script to communicate with the user and create dynamic pages.

Such as JavaScript is first recognized as LiveScript, but after that Netscape changed its name to Javascript. Thus, by utilizing HTML one can only create a web page but cannot run any logic on a web browser. Likewise, the summation of two numbers, correct any condition decision-making statement (if-else). (Cymbalta) Therefore, all these tasks cant be done by using HTML So for all these tasks we require JavaScript.

For example:



<p onclick=”myFunction(this, ‘green’)”>Click to change color.</p>

<script> function myFunction(element,colour) { element.style.color = colour; } </script>



Features of Javascript

  • Object-based scripted language
  • Handling dates and time
  • Else and if statement
  • Generating HTML content 
  • Lightweight and delicate
  • Detecting the user’s browser and OS
  • It is case sensitive
  • Ability to create functions in the script
  • Statement looping

Advantages of JavaScript

  • JavaScript is an essential part of web development.
  • Search boxes, drop-down boxes, and UI/UX design can become interactive and effectively setup with JavaScript and CSS.
  • Likewise, for web development, a server does not take a load.
  • However, JavaScript is relatively more adaptable in the time of development.
  • JavaScript is very common with programmers, so for the development of projects the resource in javascript is simpler to find.
  • There is no requirement for Annotation in code.
  • In short, Learning javascript is much easier.
  • Native Browser Support: Typescript code necessary to be compiled and the result in the JavaScript code.
  • Lastly, the JavaScript Code Flexibility is very good.

Cons of JavaScript

These are some of the cons of JavaScript -:

  • It is hard to develop complex applications in it.
  • If there is an error in JavaScript then the whole web page can stop working.
  • JavaScript code executes on the client-side, so hackers can exploit the user’s computer by using malicious code on the client-side.

Significant Differences Between C# vs JavaScript

Both C# and JavaScript are common choices in the market. Let us discuss some of the important contrast between C# and JavaScript: 

  • C sharp is not a Prototyped based language but JavaScript is a prototype-based language.
  • For web-browser Javascript is a scripting language. It also is recognized as New PHP but C sharp doe not give any feature like this.
  • However, JavaScript weakly and dynamically type but C# is strongly and statically typed.
  • Likewise, JavaScript’s initial programming paradigm is procedural but C sharp initial programming paradigm is (class-based) object-oriented.
  • C# has an integer data type whereas Javascript does not have Integer datatype.
  • C sharp supports array data type Javascript does not have array datatype.
  • JavaScript is a scripting language. C# is a compiled programming language. So due to syntactic errors at runtime JavaScript can fail.
  • In JavaScript we use function [function name]” and in C# we use void [function name]” or other function types.
  • Such as C sharp runs .NET framework and for making desktop Applications it is most beneficial on the other hand Javascript runs in a browser so for making games and quiz other application JavaScript is better.

Major Differences Between C# vs JavaScript

These are some major differences between C# and JavaScript -:


JavaScript is very slow in speed, there are not any features in JavaScript that can help JavaScript to code fast.

Whereas in opposite C# has features like dynamic typing which helps it to code fast.

So, in terms of speed C# is better than JavaScript.


C# has better readability than JavaScript.

So, if you ask C# vs JavaScript which can provide better readability, then by any second thought I can say C# can provide better readability. 

Statically Typed

C# is a Statically and Strongly Typed programming language, whereas JavaScript is a dynamically typed language.

Native Data Querying Capabilities

JavaScript has separate libraries for native data querying capabilities, whereas C# uses the .NET framework for native data querying capabilities.


C# supports multithreading whereas JavaScript does not support multithreading.

Should you learn JavaScript or C# first?

Go for C#. Unless you are planning on doing everything server-side do both. C# is a more understandable language. According to programmers learning javascript language as your primary language unless you know you’re going to be working strictly on the browser client.

C sharp is a general-purpose programming language. You can utilize it for Windows services, writing desktop apps,  robotics, mobile apps, web back ends, etc.

Another clever question can one make web apps with c#? I know CSS and HTML could you include c# with them or would you require to have Javascript?

Yes, you can utilize C# to make websites. The learning process is a little long, but you can get excited by walking through Microsoft’s Getting Started with ASP.NET MVC tutorial.

C# Vs JavaScript: Which is better for Web Development

JavaScript is used to create interactive web page, whereas C# is object-oriented programming, it is mostly used to write server code

These both have different purposes, so this is very hard to answer since both languages can be used for web development.

But if I have to choose one then JavaScript can be a better choice for web development.

JavaScript has a lot of features that help in UI design and with Node.JS it can be used for server-side codes too.

That means, JavaScript can be a better choice for Web Development.

So, In the case of web development, JavaScript has an upper hand in this C# vs JavaScript war. 

C# Vs JavaScript: Which is better for Games Development

JavaScript can be used for developing games, but when it comes to developing complex programs JavaScript can be confusing.

Whereas developing games using C# with a game engine will be a lot easier.

Moreover, you can find a lot of tutorials on the internet regarding developing games in C#, which can help you.

By this I can say, C# can be a better choice for Games development.

So, In the case of games development, C# has advantage in this C# vs JavaScript war.

In Conclusion- C# vs JavaScript

As you have seen we have mentioned features and comparisons for both the languages. Based on the above comparison between C# vs JavaScript, we can say C# is a strictly typed object-oriented programming language.

It is utilized for developing the Desktop application, console applications, and C# cannot run without .NET framework on the other hand JavaScript is a client-side scripting language essentially utilized for making interactive effects on web applications and it can perform in several web browser.
