Angular vs React: Which One to Choose in 2020?

Angular vs React Comparision

Which came first, the chicken or the egg? To be or not to be? Are zebras black or white? Angular or ReactJS? True. Choosing an ideal Javascript framework is nothing less than an uphill battle. However, with this comprehensive post on Angular vs React, we will help you choose a framework that’s right for your needs. Let’s dive deeper.

Introduction

If you know the complete web application architecture, you will find ReactJS and AngularJS don’t share much in common, they both can help you build robust and reliable web applications. Choosing one from the two is certainly a tough choice. However, with this post, we aim to clear all your doubts regarding both the frameworks. By the end of this post, you will know what’s the difference between Angular and React.

Angular vs. React JS: Brief Overview

Before we dive deeper into the nitty-gritty details about Angular and React, let’s first understand a few basics about both the frameworks.

What is AngularJS?

Developed by Google, AngularJS is an open-source, client-side JavaScript Model-View-Controller framework that can help you build dynamic web applications. It is entirely based on HTML and JavaScript. The framework was first introduced in 2010 and was later rewritten as Angular (version 2 and above) in October 2016. The latest major release is Angular 10 (released on June 24, 2020).

Popular AngularJS Use-cases

AngularJS is used extensively in web and mobile development. Here are a few of the most popular AngularJS use cases:

1.) Progressive Web Apps (PWAs)
Google itself introduced PWAs in 2015. Progressive Web Applications are websites that look and feel like an app. It’s a perfect blend of native and web apps. Today, PWAs are majorly built using Angular. In fact, Angular 5 introduced inbuilt support for PWAs to ease out the mobile development.

2.) Dynamic Apps
Dynamic apps are simply applications consisting of dynamic content. Many single-page applications are also built using AngularJS. The framework facilitates many development tools for creating dynamic apps quickly and swiftly.

3.) Enterprise Web Apps
Because Angular JavaScript contains typescript, you will be able to benefit from all the features needed to develop enterprise web apps. A few such features are advanced refactoring, navigation, and autocompletion. They will make mobile development effortless.
So, these are some of the use cases of AngularJS. Also, if you want to read the complete comparison of a website and web apps, we have also written a blog on it.

Now, we will move ahead and have a look at what is React JS and its use cases.

What is ReactJS?

Developed by Facebook, ReactJS is a front-end JavaScript library majorly used for building interactive user interfaces. It was first released in May 2013 and has been around ever since. The framework makes the code easier to understand and launch. Today, it is used for various development purposes. Let’s look at a few popular ones.

Popular ReactJS Use-cases

ReactJS has many use-cases. It’s flexibility and ease of use are two main reasons that are responsible for its rapid adoption. Here are a few popular ReactJS use-cases:

1.) Social Networks
One of the most common use cases of ReactJS would be in creating social networking sites and apps. It has all the essential features required for building dynamic web and mobile applications. No wonder why Facebook is relying so heavily on this framework.

2.) Ecommerce or Retail
You can add ReactJS as a UI library in any eCommerce web app. That’s because the framework allows you to build reusable components. Furthermore, every individual component of your web app will be independent of each other. And hence, any individual part of your app fails, you can still make it work as other features may still be operating.

3.) Cross-platform Mobile Apps
With the help of React Native, you can create stunning Android and iOS apps. Let’s say you create a website for your business. Now, with React Native, you can create a mobile app supporting it. This way, you will be able to create apps using the same architecture and methodology.

Language

  • Angular
    Angular can use both JavaScript and its superset TypeScript. In contrast to JS, TypeScript is more compact, and its code is easier to navigate. This makes the code refactoring process seamless.
  • React
    React is built on JavaScript ES6+ and JSX script — a syntax extension, making JavaScript code resemble the one written in HTML. This makes code understandable and helps spot any error easily.

Community

  • Angular
    Like ReactJS, Angular, too, has a giant community of developers, keeping the framework up to date with the latest developments. However, mastering Angular isn’t easy, and it requires a lot of time to get your hands on it. And that’s probably why not many developers are fond of this framework.With that being said, the Angular community still has millions of developers scattered across various platforms like StackOverflow, Gitter, YouTube, and Reddit. Google is the backbone of Angular, it certainly has a promising future.
  • React
    React is one of the most popular JavaScript frameworks across the globe; it has a vibrant community of millions of developers, supporting its development.If you are working with React, you will have to constantly learn as this framework would never stop evolving. There may be times when the documentation won’t be enough — because the framework is often updated, and keeping up with all the new developments can be a little challenging.

However, in such cases, you can rely on the community to get your query resolved.

Usability

  • Angular
    Angular can be used for both web and mobile development. You can use the framework for creating video streaming apps like YouTube PlayStation 3 and user-generated content portals like Upwork and New York Times. It can also be used for single- and multi-page web applications.
  • React
    React also can be used for web and mobile development. Today, it is mainly used for creating dynamic web applications including social networking sites, and eCommerce portals. Some of the famous use-cases of ReactJS would be Yahoo Mail, Khan Academy. With React, you can also create single-page and multiple-page web applications.

Testing

  • Angular
    Tools like Jasmine, Protractor, and Karma makes Angular IO testing and debugging easier. That’s not all. Angular comes with a built-in testing helper, TestBed. It also offers features like isolation of the unit of code and is written while keeping testability in mind.
  • React
    The Angular IO testing and debugging for a complete project are possible with a single tool like Jasmine, Protractor and Karma. But, this is not possible in the case of React js app development. A set of tools are required for performing different sets of testing. Skin-deep for Render testing utils, and React-unit for unit testing. Ultimately, this increases the efforts required for testing a React app.

UI Components

  • Angular
    Angular comes with a toolset and offers a wide range of material design components. You will find ample buttons, layouts, pop-ups, and forms built-in to the framework. Ultimately, this makes the UI configuration easier and seamless. It will also help you get more done in minimal time and efforts.
  • React
    React community has developed many UI tools for the framework. You can find all the free and paid UI components on the React portal. In order to use those material design components to React, you will need to install Material-UI Library & Dependencies.

Flexibility

  • Angular
    With Angular, you get limited freedom. For instance, if we talk about Angular 7, it only allows you to use Angular components inside other frameworks. As compared to React, Angular offers fewer customization options.
  • React
    React framework gives you the freedom to work with tools, and libraries of your choice. It will enable you to customize an app with the help of features and tech stack you need.

Code Quality

  • Angular
    One of the first places to look for the best Angular coding practices is the Angular Style Guide. It has everything you need to know while working with the framework. You can further enhance your code by leveraging a tool called Angular CLI. It will help you become more productive by taking away a few of the mundane tasks, like creating a project and linting your code.
  • React
    You can elevate your React code quality by using tools like ESLint and DeepScan. ESLint can help you find errors in your code and fix them for you. It can preprocess code and use custom parsers. You can also write your own rules to make it work as per your needs. DeepScan can help you find runtime errors and quality issues. It can help you improve the JavaScript code quality significantly.

Code Maintenance

  • Angular
    Single-page applications are one of the most common use cases of Angular. That’s because they are complex and have several programming modules. Maintaining them while keeping your app’s UX rich requires you to pick a framework that allows complex maintainability and can manage complex naming conventions. In such cases, Angular can help because it allows you to build maintainable JS. Furthermore, the framework also provides an HTML extension to deal with such scenarios.
  • React
    One of the most common challenges developers face is the redundancy of code. However, with React, they can reuse the code as many times as they need. The code written in ReactJS works as an independent module. This eliminates the redundancy in the code and helps developers maintain it seamlessly.

React vs. Angular Pros and Cons

Like all the top front end frameworks, React and Angular both come with their own advantages and disadvantages. Let’s quickly look over a few pros and cons of both the frameworks.

Angular Pros

  1. Trustworthy & Reliable – Because Angular is supported by Google, you can be assured that it will be maintained well and is likely to get regular upgrades. That’s not all. You can also leverage the detailed documentation and support from the massive community while working with the framework.
  2. Scalable – Angular offers seamless integration to several third-party apps and services. This means scaling up won’t be a problem while working with this framework. The developers can integrate as many tools as they wish to improve the functions of the product.
  3. Fast & Secure – Because Angular uses a concept called ‘ahead of time compiler,’ it offers exceptionally fast loading time and increased security. When it comes to Angular, it compiles HTML and TypeScript into JavaScript during development. Meaning, all the code will be compiled even before your app’s loaded by the browser.
  4. Fully Customizable – Angular elements and modules make this framework fully customizable, giving the developers the freedom to unleash their creativity. That’s not all. Angular elements can also be used for projects that are developed using another framework.
  5. Enhanced Design Architecture – A few of the large scale web applications have a lot of components. Angular can simplify the management of these components. That’s because its architecture is built in such a way that even a new developer won’t take much time to locate and develop the code easily.

Angular Cons

  1. Poor SEO – Angular offers limited SEO options. This means poor accessibility for search engine crawlers and lower rankings. However, we hope that these challenges will be addressed soon — because Google itself is the number one search engine on the planet.
  2. Longer Learning Curve – Another drawback of Angular is that it’s quite tricky to master. With so many modules, languages, and customizing options, getting a grasp of the framework could be hard initially. However, to help you get started, there are enough resources available on various platforms like YouTube and StackOverflow.
  3. Verbosity – You may hear Angular developers complaining about verbosity — the framework is complex and needs a lot of work.
  4. Too Many Versions – Angular is evolving exponentially. Something that started as a JavaScript framework is now Angular 10. The updates are very frequent. While frequent updates are good, they can overwhelm someone who is just starting. For instance, if you start your journey with Angular 10, by the time you have thoroughly mastered it, another major update may have been released. For seasoned developers, this means updating their apps to ensure they’re compatible with the latest Angular version.

React Pros

  1. Easy to Learn and Use – Working with ReactJS is easier and fun. Not only you can leverage the abundant resources, but also there are thousands of tutorials and blogs for learning React. Furthermore, if you are already familiar with JavaScript, you can start working with ReactJS in a matter of days.
  2. Creating Dynamic Web Applications Becomes Easier – Creating a dynamic web application with HTML strings was difficult and challenging. However, with ReactJS, you can create interactive and fully functional web applications with minimal coding.
  3. Reusable Components – Every ReactJS web application is composed of several components. All those components can be reused whenever needed. Ultimately, this makes web development easier and quicker. It also simplifies the maintenance of your apps.
  4. High Performance – Making your web application fast and responsive is crucial for delivering exceptional UX. When it comes to ReactJS, it interacts with a lightweight virtual DOM — which is small when compared to the real DOM. This means it can be updated fast and enables a page to fetch a response from the server in real-time.
  5. React Developer Tools – The set of tools that come with ReactJS simplify the development process while making it easier and understandable for developers. By using browser extensions, developers can easily inspect React component hierarchies in the virtual DOM. Ultimately, this accelerates the development process while reducing the timeline of the project.

React Cons

  1. The Rapid Development Pace – The constant and relentless development makes it challenging for developers to keep up with the pace. By the time they master a version of the framework, the new release is just around the corner. The ever-changing environment adds more work to the busy life of developers.
  2. Insufficient Documentation – Because the React framework receives new updates very frequently, keeping up with the documentation becomes a major challenge. You may not always find the latest information updated across the entire internet. This results in confusion and miscommunication of information among the developer community.
  3. JSX Barrier – JSX is a syntax extension used by ReactJS for mixing HTML and JS. While JSX comes with its own advantages, developers often complain about its complexity and challenging learning curve.
  4. SEO – While ReactJS apps are indexable by Google, there have been a few reports where users had to go the extra mile for making their apps searchable. Thus, if you are creating your app with React, you may consider hiring SEO experts to ensure it’s SEO-friendly and indexable.

Angular vs. React Popularity

Neither Angular or React are behind when it comes to popularity. Over the years, they both have gotten popular among various developer communities and online forums. By numbers, Angular and React stand at 66.9k and 158k stars on GitHub, respectively.

That’s not all. Both communities are very active on various technical platforms. For instance, 235246 questions have been asked on the ‘angular’ tag on Stack Overflow until now. On the other end, the ‘reactjs’ tag has received over 254356 questions so far on the same platform.

If we consider Google trends, React has received more searches than Angular. The reusable modules and shallow learning curve could be two main reasons responsible behind it. However, both the modules are equally usable and have their own use-cases.

React vs. Angular Performance

Angular
While ReactJS is perceived as a high performing framework, Angular is nowhere behind. With every new update, Angular is gradually optimizing its coding practices and elevating the overall performance one release at a time. Furthermore, adhering to best coding practices can help you take your app’s performance several notches above ordinary.

React
The most common challenge developers face while creating web applications is the inability to reuse complex logic modules. However, ReactJS resolves this challenge while allowing the developers to reuse the components repeatedly throughout the web application.

Ultimately, this not only helps developers be more productive but also allows them to optimize their coding practices. Imagine reusing a complex logic in an application whenever required. This kind of flexibility enables better performance and stability of apps.

Angular vs. React Architecture

Angular

Angular offers several amazing features out-of-the-box. A few of them are:

RxJS – It’s a library for reactive programming, making it easier to compose asynchronous or callback-based code.

Angular CLI – It’s a robust and reliable command-line interface that you can use for developing and maintaining Angular apps.

Angular Universal – It’s a pre-rendering solution that renders Angular applications on the server.

While both the frameworks offer a sound ecosystem, React is slightly easier to grasp. However, it requires several integrations to harness its full potential. And because React is a library, it can be integrated into any project — even the one written in Angular.

React

React’s approach towards creating UIs is by breaking them into small components. You create independent components that operate by themselves and then integrate them into more intricate UIs. A few of the most common tools that you may need for your React project include:

Redux – It’s a predictable state container that helps you write apps that behave consistently.

Babel – It converts JSX into JavaScript so that the browser can interact with your code.

Webpack – It is a standard module bundler.

Overall, both frameworks have a solid architecture to work with. As such, you won’t have to worry about the architecture to React and Angular.

Angular vs. React Market Share

The market share of ReactJS is significantly more than Angular. If we go by numbers, 1,041,619 websites are powered by ReactJS, and about 382,009 run on Angular. Here’s a table comparing both the frameworks:

CategoryReactJSAngular

Top 1M Websites2.874%2.884%
The Entire Web1.49%0.546%
Top 4 CountriesUnited States, China, Indonesia, United KingdomRussia, Taiwan, Denmark, Iran

How to Choose Between Angular and React?

Agreed. It’s a tough choice. Because both the frameworks can be used for creating similar web applications, picking one needs you to carefully access your requirements. For instance, if you’re seeking to build a minimum viable product with limited functions, you can go with Angular. That’s because the framework offers all the necessary components of the MVC stack to enable developers to build a fully working SPA.

On the flip side, if you’re seeking to create a large-scale single-page application with several functions, ReactJS would be the most practical choice. That’s because it will allow you to reuse your components throughout your application. Thus, it will cut the turnaround time significantly while eliminating complexity from the development process.

Angular vs. React – Which is Better?

While both the frameworks are best for what they’re developed for, they both have their own advantages and disadvantages. Having said that, we believe React is slightly better than Angular.
Not only is React more popular than Angular but also it has been evolving consistently for the past few years. Its virtual DOM implementation, rendering optimizations, and enormous support from the developer community makes it stand out.

That’s not all. If you wish to migrate from one React version to another, it’s hassle-free too! As such, you don’t have to install updates one by one — like Angular.

Summing that all up leaves us with an obvious choice – React is better than Angular in quite a few ways. This certainly doesn’t mean Angular isn’t worth it. As said earlier, both have their own positives and negatives. What you should be using really depends on your requirements and objectives.

FAQs
