Angular vs React JS

Let’s understand what is Angular and React Js, to know React vs Angular which is better.

What is Angular?

Angular is basically, an application design framework and a development platform for building efficient as well as sophisticated single page apps. These Angular docs help you learn as well as use the Angular framework and development platform, from your first application to customizing complex single- page apps for enterprises. Tutorials as well as guides include downloadable examples to expedite your project.

Angular comes under MEAN Stack Web Development which stands for Mongo DB, Express Js, Angular Js, ans Node Js.

Features of Angular

Below mentioned are the features of Angular;

DOM or Document Object Model and Angular:

The DOM (Document Object Model) treats an XML or HTML document as a tree structure. In which each node represents a part of the document. Angular uses regular DOM. Considering that ten updates are made on the same HTML page. Instead of updating the already updated ones, Angular will update the entire tree structure of the HTML tags.

Data Binding of Angular:

Angular uses two-way binding. Model state refers to any changes made to the corresponding UI elements. Conversely, the UI state reflects any change in the model state. Therefore, its feature enables the framework to bind the DOM to the model data through the controller.

Testing Framework of Angular:

Angular uses Jasmine Testing Framework as it provides various functionalities to write different kinds of test cases.

Advantages of Angular

It is profitable from both business and development standpoint. It is one of those frameworks that can work productively with different back-end languages ​​while linking together business logic and UI. Let’s see what are the advantages of Angular.

Custom Components in Angular:

It allows users to customize their own components that can pack functionality along with rendering logic into reusable pieces. It also goes well with web components.

Angular Testing:

The tests are first-class equipment. Whereas, Angular is built with test ability in mind. The person has the ability to test every part of their application, which is highly recommended.

Data Binding:

Angular enables users to easily transfer data from JavaScript code to the view, and react to user events without writing any code manually.

Browsing Compatibility of Angular:

It is cross-platform as well as it is compatible with many browsers. An Angular application can generally run on all browsers as well as OS.


Angular is a complete framework as well as it provides amazing solutions for server communication, routing within your application, and much more.

Disadvantages of Angular

Angular being an excellent Java Script framework but still it has its own disadvantages, as listed below:-

SEO options are limited in Angular:

A major drawback of using Angular is the limited SEO options of the platform and most important, it leads to poor accessibility to search engine crawlers.

Angular is difficult to learn:

With such a complex web of modules, coding languages, integration and customization capabilities, it definitely takes some time to understand Angular.

Migration and Angular:

One reason companies don’t use Angular very often is the difficulty in porting legacy JS/jQuery- based code to an Angular style architecture. Also, upgrading to each new release can be a hassle, and many of them are not backward-compatible.

Now, lets have a look at what react js is to understand react js vs angular which is better.

What is React Js?

React Js is a JavaScript-based UI development library. Which runs by Facebook as well as an open source developer community. Basically React is a library than being a language, which it is widely used in web development. The library first came out in May 2013 and is now one of the most used front-end libraries for web development.

Features of React js

Currently, React JS is rapidly gaining popularity among web developers as the best Java Script framework. Basically, it is playing an essential role in the front-end ecosystem. The most important features of React JS are as follows:


JSX stands for Java Script XML. It is a Java Script syntax extension. It is an XML or HTML-like syntax used by React JS. This syntax is processed in a Java Script call to the React framework. It extends ES6 so that HTML- like text can coexist with Java Script response codes. It is not compulsory to use JSX. But it will be good if used in React JS.

React Js Components:

React JS is all about components. A React JS application is composed of several components, moreover each component has its own logic and controls. These components can be reusable which helps you maintain the code when working on large scale projects.

One way Data Binding in React Js:

Its design is such that it follows unidirectional data flow or one-way data binding. The one-way data binding gives you a better control over the entire application. But if, the data flow is in the other direction, it requires additional features. This is because components are considered immutable and the data within them cannot be changed. Flux, is a pattern that helps to keep your data one-sided. Therefore, this makes the application more flexible leading to increased efficiency.

React Js Simplicity:

It uses JSX file which makes application with code simple as well as understandable. We know that React JS is a component-based approach which makes the code reusable as per your requirement. Altogether, it makes React Js easy to use and learn.

Performance of React Js:

React Js has great performance. The core of the framework is a virtual DOM program and provides server- side rendering, making complex apps run much faster.

Advantages of React Js

Now when we know what React Js is, let’s see what are the advantages of React Js.

Creating dynamic web applications made easy:

It was difficult to build a dynamic web application especially with HTML strings as it requires a complex coding. But, React JS solved that issue and made it easy. Basically, it provides less coding and gives you more functionality. It uses Java Script Extension, a special syntax that allows HTML quotes as well as HTML tag syntax to render special sub-components. React Js supports the creation of machine-readable code.

Reusable Components:

A React JS web application is made up of several component and each component has its own logic and controls. These components are responsible for outputting a small, reusable piece of HTML code that can be reused wherever you need it. Reusable code helps in making your apps easier to develop as well as maintain.These components can be fixed with other components to build complex applications from simple building blocks. React JS uses virtual DOM based mechanism to fill data in HTML DOM. Virtual DOM works faster because it only changes individual DOM elements instead of reloading the full DOM every time.

Easy to use as well as learn:

React JS is very easy to learn as well as to use. It comes with a good supply of documentation, tutorials as well as training resources. Any developer coming from JavaScript background can easily understand and start building web apps using React in just a few days. It is the V (view part) in the MVC (Model-View-Controller) model, and is known as one of the Java Script frameworks. It is not fully featured. But it has the advantage of the open-source Java Script user interface (UI) library, which helps in performing the task in a better way.SEO Friendly:

There is a problem dealing with SEO in traditional Java Script frameworks. Usually, for Search engines it is difficult to read heavy applications of JavaScript. Mostly, web developers have complained about this problem. React JS overcomes this problem by helping developers navigate various search engines easily. This is because React js applications can run on the server, and the virtual DOM will be rendered and returned to the browser as a regular web page.

Codes Testing:

React JS applications are extremely easy to test. It provides a scope where the developer can test as well as debug his code with the help of native tools.

Disadvantages of React Js

Nothing is perfect and this is the universal truth. Yes, the benefits of React can give the impression that the library has no flaws, but is it really? let’s find out.

Poor Documentation:

This is another common practice for constantly updated technologies. React technologies are updating and accelerating so quickly that there is no time to create proper documentation. However, to overcome this, developers write the instructions themselves in their current projects as they develop new releases and tools.

JSX acts as a barrier:

React JS uses JSX. It is a syntax extension that allows HTML to be mixed with Java Script. This approach has its advantages, but some members of the development community consider JSX to be a hindrance, especially for new developers due to its complexity.

High speed of development:

High speed of development has both advantages and disadvantages. In terms of disadvantages, because the environment constantly changes so rapidly, some developers don’t feel comfortable re-learning new ways of working on a regular basis. With all the constant updates it can be difficult for them to adapt to all these changes.

Viewed Part:

React JS only covers the UI layers of the app and nothing else. So, you still need to choose some other techniques to get a complete tooling set for development in the project.

Language Type-script basically a statically typed language which is a superset of JavaScript.Type-script can write JavaScript XML (JSX), although it is not included by default.
UI Components Material Design Components – Angular includes several Material Design components that make UI configuration a breeze.Material-UI Libraries and Dependencies – Community-developed UI tools provide a wide range of UI components.
of Apps
The architecture of Angular is MVC.The architecture of React Js is Flux.
Dependency injection is supported, allowing different life cycles for different stores.It does not fully allow dependency injection because each component has its own global state.
DOMIncremental DOM – When a new DOM is created, it compares to the previous one and applies the difference to the “real” DOM, allocating memory only if necessary.Virtual DOM – Whenever the DOM changes, a new virtual DOM is created compared to the previous one, and only the differences in the “real” DOM ​​are modified.
Its Best forThis is best for single page applications that update one view at a time.This is best for single page applications that update multiple views at a time.
Angular or React which is better

Summing up-

With so many frameworks to choose from, each with its own unique features, it can be a difficult task to choose the best.

When it comes to choose between Angular and React, its totally personal choice, as they both tackle the same problem but in different ways.

However, while choosing just keep one thing in mind that React has a steep learning curve, which leads to faster development. But, Angular provides more built-in functionality.

Both technologies are extremely powerful. A significant advancement since the early days of web programming in terms of improvements in development, convenience and speed.
