React vs Angular: the Battle for UI

One of the most challenging issues in project planning is defining the technology stack. Especially its part that will be used for the implementation of the solution interface considering its direct interaction with users.

According to SimilarTech React and Angular usage in web development differ almost in two times in favor of the first one. The question which one of them to choose arises before the start of any project which owners are aware of the latest frontend development trends.

Before stating the verdict of React Angular comparison you should dive in the profiles of both frameworks. Let’s start with the proven leader.

React.js

Origins: Facebook

Initial release: May 29, 2013

Current version: 18.2.0

UI/UX: desktop, web&mobile

Notable users: Facebook, Instagram, Netflix, NY Times.

Introduced over six years ago this Javascript library(!) gathered a large support community. it’s used for building user interfaces in successful projects for startups to enterprise-level solutions accomplished by numerous React development companies in Ukraine and worldwide.

The factor of such a success is that using it the creation of beautiful interactive UIs on different platforms became more straightforward and flexible. Let’s explore ReactJS features that outline the library advantages:

React features

UI development approach

The ability to build complex interfaces piece-by-piece was met with great appreciation by frontend developers. These code units known as Components are self-managed and define the logic of the library that what’s important based on JS, not templates.

Each of them is a part of UI and can be used multiple times for different web pages within one project saving the important development resource - time. The declarative essence of ReactJS ensures its seamless implementation and adherence to only one-way data flow simplifies the control over it making the app more flexible.

High performance and scalability

For such characteristics of web apps built using React developers and users should be thankful to Virtual DOM (Document Object Model) - the node-tree alike listing of the elements with attributes and objects (content) with properties.

This interface allows keeping and re-rendering the full UI in memory. In the actual DOM, only those components are updated and newly rendered that have been recently changed. Along with SSR support, it enables passing rich data through apps without significant performance losses and ergo gives SEO boost.

Vast application area

To decision to opt for React app development doesn’t set any limits for the rest of the technology stack giving the ability to choose actually fitting framework and not rewrite existing code. The learning and coding process is easy thanks to the ability not to stick to 100% JS but using the simple way - JSX (Javascript XML - HTML-like syntax).

All these attributes along with easy app migration make the library a prompt choice for content-based websites and diverse custom solutions including SPA and PWA. Such status outlines ReactJS eCommerce connection. Using React.js lays the suitable ground to further project extension to mobile devices with cross-platform development using React Native.

Angular

Origins: Google

Initial release: September 14, 2016

Current version: 16.0.0

UI/UX: desktop, web&mobile

Notable users: Forbes, UPS, AT&T, Samsung

Open-source cross-platform framework(! - not to be confused with the library AngularJS which it’s based on) based on Typescript - JS superset with stricter syntax and static code analysis that simplifies error location and readability.

Component-based logic is one of React and Angular similarities. But in this edition, it’s more refined and complex since the framework has a system (NgModules) that combines components and other code files with certain attributes in modules. The whole framework is more consistent making it a better choice for large-scale apps.

Angular features

Architecture type

One of the main features that attracted the dev community is MVC architecture. The Model-View-Controller pattern has wide application in modern web development because it splits and this way simplifies each layer management - data, business logic, and presentation.

Such a low-coupling structure allows arranging simultaneous development of each section and streamlining further required modifications. It also enables grouping of model views as well as related actions logically on the controller making modules less complex.

Productivity and speed

Angular has a template-based syntax that with CLI (command-line tools) speeds up UI development and covers every aspect including specifics like animations, access, and testing. It also allows reusing components for the diverse app parts and even the legacy code.

The framework uses created templates to generate code that can be easily processed by JS VM without performance losses. React vs Angular rendering? Both support SSR/CSR. So here the path to SEO optimization is also open thanks to high-speed loading. But here it’s enabled by Component Router that set up for view rendering only that code that users require now.

Diverse usability

When the app should be single-page (SPA) and large-scale, it requires a rigid structure or contains dynamic content Angular will be the appropriate choice. Since it reduces the server load it can ensure smooth performance of desktop, mobile and web solutions including PWA and hybrid apps disregarding its complexity.

The framework nature gives it the advanced status and wider applicability initially. Synchronized model-view update (two-way data binding) raises the app responsiveness and allows make real-time changes. To go a short-path with app creation using declarative templates and simple testing allows growing the community around Angular every year.

Frontend development: why React over Angular

The first question that might arise here: why to compare a library and framework in the first place?

UI libraries and frameworks

The answer is that they locked horns on the one field - the creation of user interface. And in this perspective Facebook UI toolkit finds the bigger support especially in the following aspects:

Language. Although both use Javascript in Angular the core is Typescript to use which mostly additional dev training requires. Considering that it’s not that easy-to-learn and has much more narrow distribution Angular is frequently a less optimal solution.

Migration. Unlike the easy process of changing infrastructures and versions in React, in Angular, there were noticed certain compatibility issues between editions making the update quite challenging and adding the number of adjustments to be made.

Dynamic. The framework is based on a more complicated concept setting initially more demands for the development team and its performance including project duration. The same for React Angular speed comparison - React reliance on a virtual DOM gives it an edge.

Nevertheless, Angular found its niche on the market although it's around only for three years. Despite that its community is more vibrant until the question what to choose React or Angular 2024 is relevant the competition is still on.

TO CONSIDER

Your tech stack choice shouldn’t be just based on the question React and Angular which is better? You should discover the compatibility between your project resources and needs including the whole stack specifics.

Customer retention is the key

Lorem ipsum dolor sit amet, consectetur adipiscing elit lobortis arcu enim urna adipiscing praesent velit viverra sit semper lorem eu cursus vel hendrerit elementum morbi curabitur etiam nibh justo, lorem aliquet donec sed sit mi dignissim at ante massa mattis.

  1. Neque sodales ut etiam sit amet nisl purus non tellus orci ac auctor
  2. Adipiscing elit ut aliquam purus sit amet viverra suspendisse potent
  3. Mauris commodo quis imperdiet massa tincidunt nunc pulvinar
  4. Excepteur sint occaecat cupidatat non proident sunt in culpa qui officia

What are the most relevant factors to consider?

Vitae congue eu consequat ac felis placerat vestibulum lectus mauris ultrices cursus sit amet dictum sit amet justo donec enim diam porttitor lacus luctus accumsan tortor posuere praesent tristique magna sit amet purus gravida quis blandit turpis.

Odio facilisis mauris sit amet massa vitae tortor.

Don’t overspend on growth marketing without good retention rates

  • Neque sodales ut etiam sit amet nisl purus non tellus orci ac auctor
  • Adipiscing elit ut aliquam purus sit amet viverra suspendisse potenti
  • Mauris commodo quis imperdiet massa tincidunt nunc pulvinar
  • Adipiscing elit ut aliquam purus sit amet viverra suspendisse potenti
What’s the ideal customer retention rate?
