Isomorphic JavaScript vs .NET

Isomorphic JavaScript and .NET are both frameworks for building apps, but they work in different ways. The framework you choose will have a direct impact on how an application functions, what it looks like and how easy it is to maintain. 

Which framework is going to work best depends on a number of variables. Take a look at the pros and cons for both before deciding if isomorphic JavaScript or .NET will be the best option. 

What is isomorphic JavaScript? 

Isomorphic JavaScript is a type of scripting language that allows the same code to be executed on both the client side and the server side of an application. When isomorphic JavaScript is used the server first assesses the request to an application that uses isomorphism. Only after the assessment is the request passed on to the application for processing. 

The time required to set up isomorphic JavaScript tends to be slightly longer than the time necessary to design an application that does not use this technology. Fortunately, you make up that time with less management once everything is in place. 

What is .NET?

.NET is an open-source framework for creating cross-platform desktop, web, and mobile apps. Modern, scalable, and high-performance software developments are all supported by the .NET system’s accompanying tools, libraries, and languages. The .NET platform is constantly updated and improved by its dedicated development community.

The .NET platform is a software program capable of:

  • Compiling and running programs written in .NET programming language.
  • Facilitating productive program creation with its many useful features, like reading input and displaying the current time.
  • Developing a list of acceptable data formats for storing information like text, numbers, and dates.

Pros and cons of isomorphic JavaScript

The reason more programmers are using isomorphic JavaScript is there are some key advantages that help a website perform better even if a user’s browser is outdated.  Even so, there are a few cons that have to be considered.

Pros of isomorphic Javascript


Because of their adaptability, isomorphic apps can function on any device, both old and new. Previously, SPAs’ return of JavaScript tags would cause issues for devices with earlier browser versions.


It’s common knowledge that isomorphic apps work best in browsers and that Google has begun indexing JavaScript content. Thus, isomorphic JavaScript helps enhance search engine optimization (SEO) and makes site crawling more reliable.

Less coding

Fewer lines of code are required than in single-page applications because the codes are shared between the client and server sides. Given that, far less time is needed to code.


Since the server doesn’t have to check requests constantly, efficiency is increased with JavaScript isomorphic applications’ HTML content.

Cons of isomorphic Javascript

The logic for a large portion of the application must be managed on the server side. And processing HTTP requests can be difficult, as can routing, rendering, styling, and loading modules. Another drawback is that server-side rendering requires external libraries.

Pros and cons of .NET

Isomorphic JavaScript has its advantages, but sometimes .NET is just as good if not better. You can accomplish a lot using .NET, but it may not be worth the cost if there’s a comparable alternative. 

Pros of .NET

Object-oriented approach to software development

The object-oriented methodology was originally developed to make software development more manageable by fragmenting it into smaller, more manageable components.

Simple caching system

Since developers can create a bespoke cache implementation for an app, the caching system in the .NET framework is flexible and straightforward.

Visual Studio integration

The .NET framework is integrated with Visual Studio. That means there are plenty of resources available to .NET programmers that want to create innovative web-based software. In addition, Visual Studio provides some powerful advanced compilation, debugging, and collaboration tools. 

Cross-platform development (.NET Core)

.NET Core is the best option if you create a web application that runs on macOS, Windows, and Linux without leaving the .NET environment.

Cons of .NET

Limited object-relational support

Object-relational programming is encouraged in .NET framework that enables entity framework. Although entity framework is widely used, not all developers agree that it offers enough flexibility. This is because it only supports some of the latest innovations in database design.

Unexpected expenses

Although many of .NET Foundation’s services are free, there are a few hidden fees. The annual cost of a Visual Studio license, for instance, can range from $799 to $5,999, based on the subscription period and the features you desire.

Final word on isomorphic JavaScript vs .NET

There’s a lot to think about when you’re choosing a scripting language. Some frameworks will be better than others simply based on the application you’re building or the browser that’s being used. Isomorphic JavaScript and .NET are both stable and versatile, but pricing and lack of support could give isomorphic JavaScript the edge.
