JavaScript started as a browser language and gradually, it grew further to cover technology, business domains, which proved it to be one of the most powerful programming languages. More than 67% of developers use this programming language, according to a report from Stack Overflow. 
 
Since it is a widely used language, the frameworks like Angular.js, [React.js](https://www.zenesys.com/web-development/reactjs), and Vue.js topped the list as some of the popular Javascript-based frameworks. With a rapidly changing web development, the developers don’t rely heavily on Javascript for extensive development. Blazor is a powerful technology that lets you use .NET in the browser using Blazor Webassembly. In this blog, we will compare Blazor with Angular.js, Vue.js, and React.js - the popular Javascript frameworks to find which one is better.
 
## Blazor Webassembly:

Blazor Webassembly is the most powerful component of [Microsoft Blazor](https://www.zenesys.com/web-development-services/blazor-development). It is often called WASM in short and you can execute it in the latest web browsers. This brings a lot of diversity when it comes to the programming language. WASM is the fourth language that can be natively executed in modern browsers, along with CSS, HTML, and Javascript. 
 
It features a low-level assembly language with a compact binary format. Due to this, it enables the developer to work with the code formed in multiple languages including C/C++, Java, Rust, and more. With such assembly, the apps perform similarly to native apps. 
 
Webassembly enables highly performant applications usable on web browsers. However, it is designed for integration and execution in various different environments and can also work with Javascript side by side.
 
##Features of Blazor:
 
1. The model that can build Compassable UI 
2. Enables access to latest web features
3. Build time is less and efficient
4. Dependency injection
5. Part of an open web platform 
6. Can be used on an older version of browsers
7. Enriched IntelliSense and Tooling 
8. Availability of .NET debugging
9. Rendering on the server-side
10. No plugins required
11. Real-time reloading and rendering in the browser during the development phase 

## Blazor vs. Angular.js:
 
Angular is a Javascript-based framework that was developed and released by Google in 2016. It aims to simplify the development and testing of Single-Page Applications, also known as SPA. 
 
This is achieved by the availability of the framework for client-side MVC and MVVM along with internet application features. With such a facility, the developer is enabled to build stunning SPAs in a very less amount of time. 
 
Both [Blazor](https://www.zenesys.com/blog/everything-you-should-know-about-blazor-and-its-advantages-over-javascript-frameworks) and Angular.js are open-source web frameworks. The basic difference between them is Angular.js works on the basis of Javascript and Blazor works on C#. But the important differences between the two are as follows:
 
1. Angular is into a production-ready stage while Blazor is still under development. 
2. Angular supports PWA while Blazor cannot function as server-side PWA. 
3. Blazor needs an active connection for every client and saves the component state on the server-side for each client.
4. Blazor does not come with scoped styles for components. 
As far as Angular is concerned, Tooling is in its most mature form. 
 
##Blazor vs. React.js:
 
In 2013, Facebook released React.js which is a Javascript-based UI component library. When you want to develop some of the best user interfaces that are interactive, then development using React should be preferred. This is why React was used to develop Facebook apps like Whatsapp and Instagram.
 
Facebook and a community of individual developers and corporations maintain React. Some of the famous companies that use React are Uber, Dropbox, PayPal, Twitter, Netflix, and others. The classification of Blazor vs React is “Web App builder”. React uses a detailed Javascript library to build user interfaces.

On the other hand, Blazor is an experimental framework, uses C#/Razor and HTML. The apps built using Blazor can be executed in web browsers using a Webassembly, which we discussed previously. Blazor and React, are open-source frameworks, but React is more popular than Blazor. This is because React has been around the market for a while, however, Blazor is still under development.
 
##Blazor vs. Vue.js:

Vue came into existence in 2014 and was launched by former Google employee Evan You. He developed this framework after he worked with Angular at various companies on different projects. This is why Vue is very similar to Angular from certain perspectives.
 
Along with Angular and React, Vue is also an open-source MVVM framework that can be used to build interactive user interfaces and SPA. Evan made sure that all the pain points with Angular were removed in Vue. Vue has powered popular websites like 9gag, Alibaba, Adobe, and is the second most widely used framework after React.

The most basic difference between Blazor and Vue is that Vue is based purely on Javascript while Blazor works on C#. Also, Blazor is just in the experimental phase, while Vue is a production-ready framework. Both of them being open source frameworks, Vue wins the race because of its popularity.
 
##Wrapping it Up:

Blazor is tightly integrated with .NET. The most important thing to observe here is a chance to achieve what Vue.js, React.js, and Angular.js can offer using C#. For the developers who prefer JavaScript for [web development](https://www.zenesys.com/services/web-development), then they should use React, Vue, or Angular.
 
Also, there is one fact to consider here is, the JS frameworks have evolved a great deal since their advent. But Blazor is not yet fully supported and is deficient in the features that the JS libraries can provide. There are certain reasons why React, Angular, and Vue is popular. But, the same can be applicable once Blazor is fully developed and capable to overcome all the above-mentioned frameworks.
