Angular vs React - Choosing The Best Front-end Framework

As technology roars exponentially, so does web development.  The adoptions for front-end development frameworks and libraries have become tremendously competitive.  From all the available JavaScript frameworks and libraries, React and Angular are the ones that are the most prevalent amongst the developers, and due to this, most of the people search for Angular vs React.

But how to select the best between the two?  Should you consider the project requirements to form a precise decision?  Or should you take into consideration its popularity and development time in an initial stage?  There have been loads of discussions on Angular vs React.  Let’s examine the difference between Angular and React that will help you to choose the best technology for your next or prevailing project.

A Brief

ReactJS was introduced by Facebook as a front-end JavaScript library for developing user interfaces.  React utilizes a declarative style of programming to define the UI state.  Whereas, Angular is a front-end development framework led by Google.  It is a fragment of MEAN stack and is attuned with a great number of code editors.  It is mostly considered for making dynamic web sites and apps.

Angular: At A Glance

Angular, usually denoted as Angular 2+ or Angular v2 and above, is an open-source, Typescript-based web application framework managed by the Angular Team at Google and by a community of corporations and individuals.  Angular is a thorough rewrite from the same team that developed AngularJS.

Angular is an all-inclusive term that is employed for all the versions which got released after Angular 1, comprising versions from Angular 2 to Angular 10.  Furthermore, Angular is based on Typescript – the superset of ECMAScript 6 (ES6) with lambda operators, reflection’s mechanism, or iterators, while AngularJS is completely based on JavaScript.

Angular is a framework and platform for developing single-page client apps utilizing Typescript and HTML.  The Angular framework is transcribed in TypeScript.  It exercises optional and core functionality as a set of Typescript libraries that you might import into your applications.  Released on June 24, 2020, here is a glimpse of features of the newest version, Angular 10:

  • Warnings about commonJS imports
  • New date range picker (material UI library)
  • Keeping up to date with ecosystem
  • Optional stricter arrangements
  • Removals and deprecations  
  • Novel default browser configuration

A vital part of the JavaScript network, Angular is the most well-known front end development tool to date.  Each version of Angular is feature-rich and has been advancing with smarter aspects.  Let’s take a look at the features of this extensively accepted front end framework:

  • It has Model-View-Controller (MVC) architecture and the app data is administered by model and view manages data display.  While the controller acts as a connector between the model and view layers.
  • Usually, in an MVC pattern, you can divide the app consequently and write code to associate the same.  Nevertheless, in Angular; the developers require to split up the app into MVC patterns and it does the rest on its own.  This saves a substantial amount of coding time.
  • The most operational Angular trait is the two-way data binding system.  The view layer precisely represents the model layer and it stays in impeccable synchronization.  If you do any alteration in the model, the users can have a look at the view model mechanically.  Hence, it reduces the essential development time.
  • Angular is a low code framework as compared to the rest of the front end technologies.  You do not need to transcribe separate code to connect MVC layers.  And you do not require precise code to view physically also.  In addition to this, the directives are secluded from the application code.  These all together mechanically diminish the development time.
  • Directives are the most stimulating Angular characteristics.  You can form custom HTML tags aiding as custom widgets with the assistance of directives.  Developers can utilize these to decorate behavior-driven components.  You can also operate DOM attributes as per the requirements with the aid of directives.
  • The inbuilt dependency injection of Angular makes the development of applications easier for the developers.  It asks your dependencies.  Just request it ‘I need y’, and it furnishes the same and sends it to you.

React: At A Glance

React, also termed as ReactJS or React.js is a front end, open-source, and JavaScript library for developing user interfaces or user interface components.  It is managed by Facebook and a group of companies and individual developers.  React can be utilized as a base in building mobile or single-page applications.  Nevertheless, React is concerned with sending data to Document Object Model (DOM), and so generating React apps ordinarily requires the usage of supplementary libraries for routing and state management.  React Router and Redux are examples of these libraries.

React makes it simpler to form dynamic web apps because it needs less coding and presents more functionality, as divergent to JavaScript, where coding regularly gets difficult very rapidly.  React employs virtual DOM, thus making web applications quicker.  This virtual DOM compares the components preceding states and updates the items in real DOM that were altered, instead of apprising all of the components over again, as other conventional web apps do.

The building blocks of any React application are components, and a single application typically contains manifold components.  These components have their controls and logic and can be reutilized during the course of the application, which in turn intensely lessens the application development time.  React observes a unidirectional data flow which means that when forming a React app, its developers frequently nest child components within parent components.  Since the data flows in a single way, it becomes simpler to debug errors and know where the issue occurs in an app.

Presently, ReactJS is gaining popularity as the best JavaScript framework amongst web developers.  It is having a critical role in the front-end environment.  The significant features of React JS are as follows:

  • React is all about components.  Its application is made up of several components, and every component has its own controls and logic.  Such components can be reusable which will aid you to uphold the code while working on larger scale projects.
  • JSX denotes JavaScript XML and it is a JavaScript syntax extension.  It is HTML or an XML like syntax utilized by React.  The syntax is managed into JavaScript calls of React framework.  It extends ES6 so that HTML like text can also co-exist with JavaScript react code.  It is not essential to utilize JSX, but it is suggested to use it in React.
  • React utilizes JSX files which makes the app easy to code as well as understand.  We understand that React is a component-based tactic that makes the code reusable as per your requirement.  Hence, this makes it simple to learn and use.
  • A virtual DOM object is a depiction of the original DOM object.  It functions as a one-way data binding.  When any modifications occur in a web app, the whole UI is re-rendered in a virtual DOM depiction.  Then it verifies the difference between the preceding DOM representation and the new DOM.  Once this is done, the actual DOM will apprise only the things that have altered.  This makes the application quicker, and there is no time wastage.
  • React is intended in such a way that monitors one-way data binding or the unidirectional data flow.  The advantages of one-way data binding render you better control through the app.  If the data flow in different directions, then it necessitates additional traits.  It is so because the components are supposed to be unchallengeable and the data within them cannot be altered.  Flux is a design that aids to keep your data unidirectional.  This makes the app more flexible that leads to increased efficiency.

Angular vs React: Technology Side

Angular vs React: Technology Side

Understanding the concept of Angular and React, now let’s compare Angular.js vs React JS from the technology aspect.

  1. Ease of Update

    Here, we would be observing the up-gradation procedure of React versus Angular.  Before selecting the framework, we have to ensure that it permits the addition of fresher components into the project.  Opting for an ideal framework is critical for the effective completion of a JavaScript project.  We would be equating the migration method and time that is spent for the smooth migration from the older version to the newest one.

    Angular has one major update every six months and delivers a depreciation time of six months for each release.  The update procedure is easy, and the complete framework comes with discrete bundled contributions.

    Scripts that employ React can be easily moved from older to newer API.  The APIs are fairly stable, as we see in the interface of Facebook.  The migration is quite easy and updates are smooth as contrary to Angular.  The main releases are independent and stable, but they present speedy libraries.

  2. Performance

    Performance is the most significant measure while conversing with the differences between React and Angular.  DOM is utilized for the assessment of the execution of each of the frameworks.  DOM is a programming interface that systematizes the XHTML HTML, and XML documents in the form of a tree.  The tree then permits the scripts to interrelate with each other vigorously.

    Angular utilizes real DOM for its apps.  For single-pages that get rationalized sometimes, real DOM is impeccable.  Also, the extent of the library is enormous, which creates the apps utilizing Angular sluggish.  For instance, UpWork is one of the most prevalent apps that employ Angular, as the necessity for regular updates of users’ feed is low.

    React utilizes a virtual DOM and is perfectly suitable for pages that require frequent content updates.  The scope of the library is trivial, which makes it more dynamic and lightweight.  For instance, Instagram utilizes React as it requires the user feed to update recurrently.

  3. Performance and Flexibility

    There is a significant difference between React and Angular in terms of the flexibility offered.  React offers the developers numerous libraries, tools, and varying patterns to opt from.  A skillful React team can opt for the tools they require at the commencement and present an extremely customized app.

    Angular does not offer the flexibility that React JS does.  Angular elements can be utilized only within other frameworks, and codes have to be rooted within an HTML app.  This rigidness does not assist apps that need real-time updates to be noticeable.  Furthermore, the most stimulating thing that you will observe in Angular is that each component has a lifecycle, known as the Angular lifecycle.

  4. Virtual DOM vs Regular DOM

    DOM is an imperative metric in the performance assessment of each of the frameworks.  As we have seen earlier, DOM systematizes the XML and HTML documents in the form of a tree.  In Angular applications, a real DOM is utilized, which means the complete tree structure is restored when a single alteration is made.  This makes the procedure slower.

    Though, React utilizes a Virtual DOM, which permits the developers to make alterations to the tree without the requirement to update the complete tree.

  5. Data Binding

    The Angular framework utilizes a two-way binding method that alters the model state mechanically when any modification is made in the UI elements and vice versa.  The React library employs a one-way method. This method permits the modification in UI elements only after alteration is made in the model state.  The two-way method seems to be simpler, but React’s one-way method is more active for the projects with huge amounts of coding.

  6. Developer’s Perspective

    Angular is simple to step up but it takes time to convey projects since it has a precipitous learning curve and utilizes a lot of needless syntax for the simplest aspects.  Hence, it increases the coding time and delays the project deliveries.

    React, generally, takes a longer time to set up than Angular but permits you to form projects and develop applications relatively rapidly.  Furthermore, you can add novel features to React through dissimilar libraries.  It also has a deficiency of controller and model components, unlike Angular.


Difference Between Angular and React

Although both the frameworks utilize component-based patterns and hence, share many resemblances, they also vary in various ways.  Let’s take a closer look at React vs Angular.

AspectAngularReact
Type The full-fledged framework presents a strong opinion on how your app must be organized and has numerous small libraries inbuilt that aids you develop complex apps. It is a library and cares only about View on MVC pattern. It needs Flux to device this architecture but renders you more freedom the way you need to form the code.
Language Typescript – a superset of JavaScript and statically entered language. JavaScript XML (JSX) – can be transcribed in Typescript, though not natively.
Data binding It has a two-way data binding which means that if we alter the input in the UI it will modify the model state and vice versa. It has one-way data binding which means that a UI element cannot alter the state of the component.
DOM Incremental DOM – when forming a new DOM it will associate with the previous one and apply the differences to the ‘real’ DOM, only assigning the memory if essential. Virtual DOM – whenever the DOM alters it will form a new virtual DOM, compared with the previous one and only alter the ‘real’ DOM where it varies.
Testing Jasmine and Mocha. Jest and Enzyme.
Usage You must utilize Typescript. You can utilize JavaScript, and ES6/7, though you can employ Flow or Typescript if you so choose.
Scalability Easy to scale. Easy to scale and more testable.
Popularity Its popularity has dropped since AngularJS. Its popularity has increased exponentially.
Employed by It is employed by Forbes, Nike, Google, Upwork, HBO, General Motors, and Sony. It is employed by Airbnb, Facebook, Netflix, Uber, Instagram, Dropbox, and Whatsapp.
Learning curve The learning curve is higher, but once you comprehend it, you have a complete MVC framework. The learning curve is comparatively lower, but you only get the view. Due to this, you are going to have to learn a bundle of third party libraries.
Size It is larger in size, resulting in extended load times and performance on mobile. It is smaller in size than Angular, so it is a bit faster.
