What is React?
React is a free and open-source front-end JavaScript library for building user interfaces based on components. It is maintained by Meta (formerly Facebook) and a community of individual developers and companies.
React is a JavaScript library that aims to simplify the development of visual interfaces.
Higher Order Reach Component: This represents the entry point of the React application, possibly a wrapper component that manages the overall application state and logic.
User Interface (React Component): This section shows the user interface components that the user interacts with directly. It could be individual components or container components that group smaller components.
Request Module: This depicts the component responsible for handling user actions and initiating data requests. It likely sends requests to the server or utilizes an API.
Action: This represents the user's action that triggers the data request, such as clicking a button or submitting a form.
New State: This shows the updated application state after the data request is processed. It could be stored in Redux or another state management library.
Single Source of Truth, Middleware, Redux Store: This block indicates the central storage of the application state, likely managed by Redux or a similar library. Middleware functions can intercept and process actions before they update the state.
Cache: This represents a component or service that temporarily stores frequently accessed data for faster retrieval, improving performance.
Reducers: These are functions responsible for handling specific actions and updating the state accordingly, ensuring predictable state changes.
Middleware: This layer intercepts actions before they reach reducers, enabling additional processing, logging, or side effects like fetching data.
http request & http response: These arrows depict the communication between the application and the server. The app sends HTTP requests for data and receives HTTP responses with the requested information.
Service End Points & OData Services: These represent the server-side APIs or services that provide data to the application. OData is a specific protocol for accessing and manipulating data over the web.
Advantages:
Component-based: Reusability and easier maintenance.
Virtual DOM: Performance optimization and smoother UI updates.
Large community and ecosystem: Extensive libraries, tools, and support.
Flexible: Adaptable to diverse project requirements.
SEO-friendly: Server-side rendering options are available.
Disadvantages:
Steeper learning curve: Requires understanding of JSX and state management.
Potential for larger bundle sizes: Can impact page load times.
Lack of built-in features: Requires additional libraries for data binding, routing, etc.
Opinionated approach: Requires adherence to specific patterns and conventions.
Real-world examples:
Facebook
Instagram
Netflix
Twitter
Uber
Future Trends:
React 18 was released in 2022 with new features like automatic batching, server components, and the ability to define asynchronous rendering boundaries. The demand for React.js skills has increased steadily in recent years.
What is Vue?
Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adaptable. The core library is focused on the view layer only and is easy to pick up and integrate with other libraries or existing projects. Vue.js is an open-source JavaScript framework, crafted with precision by Facebook, that aims to simplify the intricate process of building interactive user interfaces.
ViewModel: This represents the central component in Vue.js, serving as the bridge between the View (UI) and the Model (data). It manages the data, defines computed properties and methods, and exposes them to the View for rendering.
View: This represents the user interface, composed of HTML templates with data bindings and directives. The ViewModel dictates the structure and content of the View through bindings and updates the View automatically whenever the data changes.
Model: This represents the application's data, often stored in plain JavaScript objects or arrays. The ViewModel interacts with the Model to retrieve and update data, influencing the displayed UI.
Data Bindings: These are directives that connect data in the ViewModel with elements in the View. Changes in the data automatically trigger updates in the corresponding UI elements, and vice versa.
Directives: These are special attributes prefixed with v- that provide additional functionalities beyond HTML, such as conditional rendering, loops, and event handling. They enhance the capabilities of the View and simplify interactions with the ViewModel.
Lifecycle Hooks: These are methods in the ViewModel that get called at specific stages of a component's lifecycle (e.g., mounted, updated, destroyed). They allow developers to perform custom actions at these key points, such as fetching data or performing side effects.
Event Listeners: These are functions that react to user interactions on the View (e.g., clicks, key presses). They can be defined in the ViewModel and are used to update data or trigger actions based on user input.
Advantages:
Easiest to learn: Gentle learning curve with simple syntax and clear documentation.
Progressive: Can be used for small or large projects, incrementally.
Built-in features: Two-way data binding, virtual DOM, routing, and more.
Lightweight and performant: Ideal for smaller projects and SPAs.
Flexible and adaptable: Integrates well with other libraries and frameworks.
Disadvantages:
Smaller community and ecosystem: Compared to React, fewer libraries and resources.
May lack structure for complex projects: This can lead to code inconsistencies if not managed well.
Potential for boilerplate code: Depending on project needs, additional configuration might be necessary.
Less mature than React and Angular: May have fewer battle-tested solutions for specific problems.

Spendesk, Moderne
Chargebee, Yousign,
Infermedica, Keap
Beau
Laravel Vapor
MetaMusic
Specify
ProtoPie
Future trends:
Vue 3 had several improvements that could influence trends in JS frameworks in 2024. Vue’s popularity is reflected in its widespread usage across various industries.
What is Angular?
Angular is a development platform, built on TypeScript. As a platform, Angular includes a component-based framework for building scalable web applications, a collection of well-integrated libraries that cover a wide variety of features, including routing, forms management, client-server communication, and more.
AngularJS is a JavaScript framework that web developers use to create single-page web apps.
Components: Represented by boxes with curly braces, these are the building blocks of the UI, each managing a specific view with its own template and logic.
Services: Shown as boxes without curly braces, these are background tasks not directly tied to the UI and can be shared across components.
Modules: Not explicitly shown, but they're likely implied by the groupings of components and services. Modules bundle related functionalities together.
Data Binding: The two-way arrows between components and elements like "Property Binding" and "Event Binding" depict how data flows between the UI and components.
Metadata: The "@Component" and "@NgModule" decorators applied to components and modules define their configuration and behavior.
Directives: Not explicitly labeled, but potentially represented by the "Fn" and "< >" elements, these are reusable code blocks that manipulate the DOM or component behavior.
Template: The HTML code within the "< >" brackets defines the UI structure for each component.
Injectors: Not directly shown, but conceptually represented by the arrows injecting "Services" into components, they manage dependency injection, providing components with the services they need.
Advantages:
Structured and opinionated: Enforces best practices and leads to clean, maintainable code.
Robust tooling and features: Built-in routing, forms, dependency injection, and more.
Scalable and performant: Well-suited for large enterprise applications.
Mature and stable: Extensive documentation and well-established community.
TypeScript integration: Offers strong typing and static code analysis for improved code quality.
Disadvantages:
Steepest learning curve: Complex architecture and TypeScript requirement.
Heavyweight framework: This can be overkill for smaller projects.
Less flexible: Opinionated structure might limit customization options.
Larger bundle sizes: Can impact page load times.
Potentially slower development: More upfront configuration and learning involved.
Real-world examples:
Gmail
PayPal
Deutsche Bank
Future trends:
Angular provides an excellent set of functionalities out of the box, including data binding, dependency injection, and component-based design8. Angular 13 introduced support for advanced browser features like the web animations API, better build performance, and updates to the Material UI library.
