In May 2021 Stack Overflow conducted a survey on over 80,000 developers and according to this Developer Survey:
Let’s move on to the next section without further ado:
What is ReactJS?
History of ReactJS:
Key Features of ReactJS:
i) Virtual Dom: React make use of Virtual DOM representation for every DOM object. When changes are made in the webpage Virtual DOM gets updated instead of the real DOM and renders only those components that have changed instead of rendering the whole page. Manipulating the Virtual DOM is quicker rather than updating the original DOM. Hence it proffers blazing fast speed and better user experience. Additionally, React Native popular mobile development framework has built on the concept of React; and ReactJS consolidated with other web technologies for desktop application and backend development.
iii) Unidirectional Data Flow: React is designed in such a way, that it only supports downstream one-directional data flow architecture. The one-way data flow has some key advantages such as any changes to the child component will not affect its parent, siblings or any other component thus it ensures less error, easier to debug, and a more efficient development environment. If there is any need to flow data in another direction, the additional features need to be applied.
Websites Built with React:
Studies show, at present more than 300k websites are implementing the ReactJS framework. Almost every single large tech company such as Microsoft, Yahoo, Facebook, Airbnb, Twitter is using React.

What is VueJS:
Vue.js is an open-source front-end for creating user interfaces, single-page web applications(SPAs), and progressive web applications (PWA).
It combines the features of AngularJS and React.js and made huge improvements on the features to deliver a more efficient and improved development technology. It has Virtual DOM traits like ReactJS for state management and two-way data binding like AngularJS for sharing & updating data simultaneously between the component classes and their templates.
In consequence, VueJS gained widespread fame as a flexible, multifaceted, and one of the easiest front-end frameworks to learn and implement.
History of VueJS:
Vue.js was designed by an ex-Google engineer named Evan You and released in 2014.
Key Features of VueJS:
Only the final changes are made to the real DOM and the changes will run on the user-end screen. This creative feature ensures better performance and cost-saving production.
ii) Data Binding: This feature enables to manipulation of the HTML interface with the help of a binding directive called v-bind.
iv) Computed Properties & Watchers: Computed Properties is one of the powerful features of VueJS. It allows to transformation or performs necessary calculations on data responding to the changes of UI elements without any additional coding. The result can be reused in the template as an up-to-date variable.
The watcher property of VueJS provides a more generic way to react to data changes through the watch option. Custom Watchers are applied for handling data that changes frequently. This reactive feature of VueJS plays a great role in performing asynchronous and expensive operations in response to changing data without any need for additional coding.
v) Components & Custom Directives: Components are reusable Vue instances that allow to encapsulate and reuse functionality in an application. Components have their own view and data logic for creating custom elements; these elements can be reused in HTML. Vue directives are used to perform front-end functions and to manipulate the DOM behavior. VueJS has several built-in directives such as v-if, v-else, v-show, v-on, v-bind, and v-model. besides, Vue also allows you to register your own custom directives where you need some low-level DOM access on plain elements.
Websites built with VueJS:
Studies show, at present more than 720k websites are implementing the VueJS framework. Largest companies like Xiaomi, UpWork, Adobe, Apple, BMW, Louis Vuitton, Nintendo Grammarly are using Vue.

What is AngularJS:
AngularJS comes with everything you need to build a CRUD app in a cohesive set: Data-binding, basic templating directives, form validation, routing, deep-linking, reusable components, dependency injection, and so forth.
History of AngulaJS:
AngularJS or Angular 1 was designed by Google’s engineers Misko Hevery and Adam Abrons in 2010. Later AngularJS was completely redesigned because of its shortcomings and re-released in 2016. It is currently powered by Google.
Key Features of AngulaJS:
i) Model-View-Controller(MVC): AngularJS is established on the concept of M-V-C architecture. MVC is a design pattern for dividing an application into different parts called Model, View, and Controller. In the MVC pattern, the app logic layer, data layer, and presentation layer(UI) are separated from each other; thus MVC with AngularJS provides an easier and more managed way to develop applications.
ii) Data Model Binding: One of the significant features of AngularJS is 2-way data binding. AngularJS data binding model forms a connection between model components and view components for automatic synchronization. so any changes in the model layer will reflect in the view layer automatically and vice versa. Hence there is no need of writing additional code to bind data between these two-layer.
iii) Directives: AngularJS extends HTML language with ng-directives and provides extra functionality. Directives are markers on a DOM element such as an attribute, element name, comment, or CSS class. Angular allows you to create custom directives with the .directive function that can serve as a new, custom widget. AngularJS has built-in directives such as ng-blind, ng-model, ng-app, ng-init, etc.
iv) Templates: AngularJS framework allows to use of templates that are written with plain HTML that contains AngularJS-specific elements and attributes. HTML can be extended to include instructions to render corresponding model components on the view layer. Templates combined the model and controller to manipulate the end-user view. Angular templates also support to control of CSS, Forms, Filters, and Expressions.
On top of that, AngularJS Template introduces an efficient way to collaborate between the designer and developer work. Designers can mark up their HTML and developers can take care of implementing the functionality with ease.
v) Dependency Injection(DI): AngularJS has a built-in Dependency Injection(DI) subsystem. DI sub-system is in charge of creating components, resolving their dependencies, and providing them to other components as requested. whenever you need a core angularJS service Dependency Injection allows you to call your dependencies and the DI subsystem handles everything to create and provide it to you. Thanks to the Dependency Injection feature of AngularJS for facilitating the developer to create, understand and test applications easily.
Websites Built with AngularJS:
Studies show, at present more than one million websites are implementing the AngularJS framework. Giant companies like Microsoft, Forbes, Google, IBM are using AngularJS.

What is EmberJS:
Powerful characteristics of this full-featured opinionated framework are two-way data binding, debugging tool called Ember Inspector, Ember Command-line interface tool, Convention over Configuration(CoC) approach, and built-in development environment, etc.; all these provide a scalable UI architecture and a standard methodology to build modern web applications. It introduces a complete development stack for boosting developers' productivity.
History of EmberJS:
EmberJS was designed by Apple’s Yehuda Katz in 2011 and launched in 2012. Ember was originally a SproutCore 2.0 framework that was later renamed Ember.js.
Key Features of EmberJS:
i) Ember CLI: One of the most highly valued features of Ember is the Ember Command-line interface tool. It is a robust development toolkit to create, develop, build, test, and serve the files that make up an Ember app or addon. Ember CLI helps you to start with zero configuration; even Ember CLI comes with a help system that allows you to know about any command and its functions with the help command. Ember CLI also helps to install dependencies from third-party libraries.
ii) Routing: The routes are core features of Ember.js which are used for managing the URLs. Enables developers to drive the application state from the URL.
iv) Services: An Ember Service is a long-lived object used to provide services to other Ember objects. once a service is formulated, it will live for the duration of the applications' lifecycle and can be made available in different parts of your application. Services can be generated using Ember CLI's service generator object and Services must extend the Service base class to reuse the service properties.
v) Ember Inspector: Ember.js offers a debugging tool called Ember Inspector. The Ember Inspector is a browser add-on that helps monitor and debugs the ember applications live. This debugging tool is compatible with all browsers and you can install it on Google Chrome, Firefox, and other browsers (via a bookmarklet).
Websites Built with Ember.js:
Studies show, at present Approx. 32k – 36k websites are implementing the Ember.js framework. A notable number of big tech companies utilizing this framework including Microsoft, LinkedIn, Netflix, Twitch, Heroku, Square, Intercom, TED, etc

Introduction to SvelteJS
SvelteJS is an open-source, component-based framework for building user interfaces and enhanced web apps. SvelteJS is written in TypeScript.
key features of SvelteJS
ii) Client and server-side rendering: Svelte supports client-side as well as server-side rendering.
iii) Developer-friendly: Fullfledge framework with a big toolbox to help develop faster. It requires less code; writing more code means it takes time, effort and the apps will be buggier. Here, Svelte comes with the goal to reduce the amount of code you have to write
v) Easy integration and interoperability: Svelte is simply a compiler. Svelte works at the component level and so, even if your project already uses Vue or React, you can simply integrate Svelte components with it. In svelte code, splitting is much easier than other frameworks.
Websites Built with SvelteJS:
Studies show, at present ApproxApprox. 3600 websites(live and historical) are built with SvelteJS. To name a few of them are Godaddy, Razorpay, 1password, and New York Times.
