React vs Angular

Out of all the front end development frameworks in the market, the two that have found a place in the list of Top 15 JS Frameworks for 2019 are React and Angular. And this article is concentrated on them both.

In the next … minutes, you will be reading about what separates Angular and React from each other, the situations where a react native app development company get brownie points and where brands focus their energy on Angular app development.

The reason why we are concentrating this article on the comparison of Angular js and React is partially because, they come from a lineage of two solid competitors – Google and Facebook and partially because we had already covered React vs Flutter – the newest addition in the framework family, so it was time to compare React with a brand that has established itself in the industry at the back of its unmatched performance.

Before we move even a step ahead, let us glance through the synopsis of React and Angular Frameworks –

To start with, Here’s a table of comparison showcasing the difference between the two most popular and widely adopted JavaScript Libraries – Angularjs vs Reactjs –

React Native vs Angular Comparison

While the table highlights where both the frameworks lie on every individual factors, it doesn’t explain which one to choose between Angularjs and Reactjs, requirement wise.

Let us answer that into some detail.


It is the capability to run and then deploy a code the way you want it. For achieving faster load time, we developers aim at loading the minimum at first and then continue on the basis of the demand. It also give us the capability to develop features without having to degrade the loading time.

Angularjs offers restricted ability to do this and when you still go ahead with the process, it ends up looking like an assembly code.

In other words, Angular is too rigid. While React on the other hand allows the developers to make use of the requirejs for lazy loading the pieces of code. The framework also enables working with solutions such as webpack.

Our Verdict – React

Learning Curve

Angularjs is not easy to master. I am sure you will be getting my point if you are a developer.
Angular comes with a very complex lifecycle and for you to master it you will have to read code, deal with the un-intuitive link and compile – all making Angularjs learning curve very high.

While Angularjs learning curve is on the higher side, React, on the other side, comes with a low learning curve even though it takes time for developers to get use to one-way flow. Also, the framework has very few lifecycle methods and the fact that you hardly ever have to read the code is what takes it home for React.

Our Verdict – React

Model Complexity

It means how you structure your data model which is then represented by view. The performance of Angular is considered very sensitive when it deal with scope cause of the copy-n-compare option, which means that it restricts you from using large models – an outcome that comes with the advantage of making the code simple and testable. React, on the other hand, give you the option to choose without putting any performance penalty.

Our Verdict – It’s a Tie. Both Angularjs and Reactjs are equally well.

Reuse of Code

Angular comes with a series of ready to use elements, even though it is not very trivial to make use of the Angular Libraries coming in from more than one specific provider because of the priority collisions and the namespaces.
React on the other hand, lets you manage the code as you like. But the fact that Angular comes with more ready to employ elements, give bounty points to the library as compared to the React framework.

Our Verdict – Angularjs


Templates a.k.a The building blocks of the app logic have a lot of custom flows and information and are developed with the help of ready made building blocks, however they are never really re-usable. Templating in React are not as clear as that of Angular.

The React Native Templating looks like this –

While the Angular Templating looks like this –

Our Verdict – Clearly Angular

Now that we have compared both the frameworks on several elements, we can see that even when Angularjs learning curve is pretty high, it is not keeping developers from following it.

And now, an article of comparison between Angular and React will remain incomplete without looking into the advantage and disadvantage that the frameworks come packed with.

Advantages and Disadvantages of React and Angular App Development

Advantage of Angularjs

If we look at the community and developer support as the advantage measuring factor, there is no other JavaScript framework that come with a community support like Angularjs – a factor that has brought in a rise in demand for the framework.

Advantage of Angularjs

The framework runs on all the browser environment irrespective of the platforms. Along with that, Angularjs includes the off-the-rack tools and it has established itself as a reliable framework with robust ng components which are evolved in juxtapose.

The Bi-Directional Data Binding is the feature that sets Angular aparts from React, solely because it disperse influence after every set of the data changes.

Disadvantage of Angularjs

The absence of a clear manual and all inclusive extensive documentation, along with the steep Angularjs learning curve are the main limitations of the popular JavaScript  framework.

Advantage of Reactjs

React comes with JSX, which allows use of HTML codes and practicing of HTML tag syntax for subcomponents rendering. It also promotes the development of the machine readable programs and offer the ability to compound the components in single compile-time file.
The factor that React comes with make it an ideal setup for mobile app development has led to a number of developers downloading React Native for Mobile App Development.

Apart from a lower learning curve that is opposite of the case of Angularjs learning curve, a prompt rendering feature of React gives it an edge over Angular framework. It involves different approaches to lower the amount of DOM operation, betters and hastens the update process.
Virtual DOM is also of use as developers manage the large database.

The number on differentiator between React and Angular is that Angular is a subset of HTML, while React is a purely JavaScript based framework. Now, JS is considered a more advanced language when compared to Angular, making React the choice when you are looking for a simple, dependable, and intensive programming.

Disadvantage of Reactjs

Integrating Reactjs in the traditional MVC framework like Rail requires configuration, an event that slows the development time.

The combination of advantage and disadvantage that both the frameworks come with, make them suitable for use in some use case scenario and unsuitable for others.

Let’s take a look at what those use cases are where React js app development make sense and where Angular app development would be a better fit –

When to Use which JavaScript Framework

When to use Angularjs

Use Angular when you need your app to be compatible with browsers that are older than the IE8. Also, with Angular 5.0 in the market, the framework has been witnessing a lot more attention from the developers, especially with the performance boost and the feature of server side rendering support.
If the complexity level of your app lies in the range of low to medium, Angularjs would be the right choice.

When to use React

React is the right choice when there are a number of dynamic content in your app inside the view. This is the reason why brands like Facebook and Instagram use React to base their mobile apps on.

With this, you now know the situations where adopting React makes sense and places where Angular is a better fit.
Here are the brands that, keeping the different situations in mind, have adopted the frameworks –

Now that you know which brands are using which Framework, I am sure you must have taken a decision on which framework you will be going with for your next mobile app project.

Whatever decision you take in terms of the framework choice on the first look of it, there are certain factors that you should consider while taking the decision.

Things to Consider Before You Make the Decision

Here are the different factors that you will have to consider while making the React vs Angular decision.

Things to Consider Before You Make the Decision between React and Angular


Libraries are Frameworks are distributed with different licenses. While some licenses are fairly flexible and allows adjustment in accordance to the requirements, a kind known as Open-Source Products. There are others that don’t allow creation of commercial apps or the flexibility of editing the content.
Now, both React and Angularjs are open source, meaning you cannot use the name of right holder for the purpose of advertising.

MVC Pattern

The ease of dividing the app data in easily modifiable and readable elements helps with reducing the line of codes and in increasing the quality of the end product. Angular is developed on the MVC architecture while React only has the View component of MVC, which increases the line of codes.


When you develop a JS product, you would want to take advantage of the templates that are used to create UIs. Angularjs use template in TypeScript file while React make use of templating in the JSX file.

Data Binding

The feature help establish connection between business logic of app and the UI. While Angular uses two-way data binding allowing the framework to connect Model Data to DOM through the controller, affecting the app performance; React only implement one-way binding of data. When the data is only directed one way, the debugging of app becomes a lot easier, especially for large applications.


There are two ways to render data – server side and client side. Client side rendering affects the page loading time inversely, so it’s prefered that you use framework that has server side rendering – something that both React and Angular uses.


Angular comes with two way data binding that influences performances when you talk about the development of complex apps, while when you use React, you don’t face this issue. In addition to that, Reactjs app developers have added in a virtual DOM feature which allows creation of light DOM tree and saving that on server, which leads to lowering the load on browser.

Now that we have covered the different aspects of the frameworks’ present, we have now arrived at a point where we look at the future of the Angular and React JavaScript Frameworks. Let us look at what the future holds for each.

What does the Future of both React and Angularjs holds

The short version is that none of the frameworks will go out of picture by next year or even 2025. React will continue to see a rise in popularity, making it a default starting point for developers. While Angular on the other hand, has already been witnessing a growth in the usage rate.

So while both the frameworks are on a growth tangent, there is one framework that is preparing to take their place in the mobile app development world – Vue.js. And this is the long version of our take on which framework will stand the test of time.

Both React and Angular will but they will a stiff competition coming in from Vue.js.
