  1. React Created by Facebook, the React framework has earned popularity within a short period. It is used to develop and operate the dynamic User Interface of the web pages with high incoming traffic. It makes the use of a virtual DOM, and hence, the integration of the same with any application is more straightforward.

Declarative: Creates interactive and dynamic UI for websites and mobile applications. React updates efficiently and render the right components when data changes. Declarative views make the code readable and easy to debug.
Virtual DOM: For every DOM object, there is a corresponding "virtual DOM object." It creates a virtual copy of the original DOM and is a representation of a DOM object,
Event handling: React has its fully compatible W3C object model event system created. It also provides a cross-browser interface to a native event, meaning no need to worry about incompatible event names and fields. React reduces memory head by as event system is implemented through event delegation and has a pool of event objects.
JSX: JSX is a markup syntax that closely resembles HTML. JSX makes writing React components easier by making the syntax almost identical to the HTML injected into the web page.
Performance: React uses one-way data binding with an application architecture called Flux controls. ReactJS helps update the View for the user and, Flux controls the application workflow. Virtual DOM adds advantages as it compares the new data with original DOM and updates the View automatically.
React Native: React Native is a custom renderer for React; it uses native components instead of web components like React as building blocks. It also serves access to these platforms' features, apart from transforming React code to work on iOS and Android.
Component-Based: In React, everything is a component of the web page divided into small components to create a view(or UIs). Every part of the application visuals would be wrapped inside a self-contained module known as a component. Components in ReactJS use to define the visuals

  1. Angular Angular - JavaScript Framework One of the most powerful, efficient, and open-source JavaScript frameworks is Angular. Google operates this framework and is implemented to use for developing a Single Page Application (SPA). It extends the HTML into the application and interprets the attributes to perform data binding.


Progressive Web Apps: Modern web platform capabilities to deliver app-like experiences that are high performance, offline, and zero-step installation.
Native: Strategies from Cordova, Ionic, or NativeScript are used to build the native app.
Desktop: Desktop-installed apps across Mac, Windows, and Linux can be created using the same Angular methods like the web plus the ability to access native OS APIs.
Speed and Performance

Code Generation: Angular turns templates into code that's highly optimized for JavaScript virtual machines, giving hand-written code benefits.
Universal: Serve the first view of Node.js, .NET, PHP, and other servers for near-instant rendering in just HTML and CSS.
Code Splitting: With the new Component Router, angular apps load quickly, delivering automatic code-splitting. So users load the code required to render the view they request.

Templates: Create UI views with simple and powerful template syntax.
Angular CLI: Command line tools: start building fast, add components and tests, then instantly deploy.
IDEs: Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs.
Full Development Story

Testing: Protractor makes your scenario tests run faster and in a stable manner.
Animation: Create high-performance, complex choreographies, and animation timelines with very little code through Angular's intuitive API.
Accessibility: Create accessible applications with ARIA-enabled components, developer guides, and built-in a11y test infrastructure.

  1. Vue.js Vue - JavaScript Framework Though developed in the year 2016, this JavaScript framework has already made its way into the market and has proven its worth by offering various features. Its dual integration mode is one of the most attractive features for creating high-end SPA or Single Page Application. It is a much reliable platform for developing cross-platform.

Virtual DOM: Vue.js utilizes virtual DOM. Virtual DOM is a clone of the principal DOM element. The virtual DOM absorbs every change intended for the DOM presents in the form of JavaScript data structures, which are compared with the original data structure.
The viewers view final changes that reflect in the real DOM. The method is creative and cost-effective; also, the changes are done quickly.
Data Binding: This feature facilitates to manipulate or assign values to HTML attributes., change the style, assign classes with v-bind available, which is a binding directive.
CSS Transitions and Animations: This feature provides several methods to apply a transition to HTML elements when added, updated, or removed from the DOM. Its features consist of a built-in component that wraps the element responsible for returning the transition effect.
Template: It provides HTML-based templates that bind the DOM with the Vue.js instance data. The templates are compiled into Virtual DOM Render functions. A developer can use the render functions template and can replace the template with the render function.
Methods: We use methods when an event occurs that isn’t necessarily related to the instance data being mutated or want to change a component’s state. Methods do not keep records of any dependencies but can take arguments.
Complexity: Vue.js is simpler in terms of API and design. A web developer builds simple applications in a single day.
