Virtual DOM: One of React’s key features is its virtual DOM, which is a lightweight representation of the actual DOM. React compares the virtual DOM with the real DOM and only updates the parts of the DOM that have changed, resulting in improved performance and faster rendering of UI updates.

JSX Syntax: In React, JSX (JavaScript XML) syntax is employed, empowering developers to craft code reminiscent of HTML within JavaScript. This declarative syntax streamlines the creation and manipulation of UI components, blurring the distinction between HTML and JavaScript.

One-Way Data Flow: React follows a unidirectional data flow, where data flows downwards from parent components to child components via props. This ensures predictable data flow and makes it easier to reason about the state of the application.

Component Lifecycle Methods: React furnishes developers with a series of lifecycle methods, granting them access to different stages of a component’s lifecycle. These stages encompass initialization, rendering, updating, and unmounting. By leveraging these lifecycle methods, developers can execute various tasks, including fetching data, updating the user interface, and tidying up resources.

2. Vue.js:

Reactive Data Model: Vue.js employs a reactive data model, where the UI reacts to changes in the underlying data. When data changes, Vue automatically updates the corresponding parts of the UI, ensuring a seamless and reactive user experience.

Computed Properties and Watchers: Vue.js provides computed properties and watchers, which allow developers to perform complex data transformations and react to changes in data asynchronously. Computed properties cache the result based on their dependencies, while watchers listen for changes to specific data properties and trigger side effects accordingly.

Component Composition: Vue.js embraces a component-based architecture similar to React, where UIs are composed of reusable components. Vue components encapsulate HTML, CSS, and JavaScript logic into a single, self-contained unit, making it easier to develop and maintain complex UIs.

Props and Events: Vue.js uses props to pass data from parent components to child components, similar to React. Additionally, Vue supports event handling, allowing child components to communicate with parent components via custom events.

Single-File Components and Vue CLI: Vue.js introduces the concept of single-file components, where HTML, CSS, and JavaScript are encapsulated into a single file with a .vue extension. Vue CLI simplifies project setup and development by providing a command-line interface for scaffolding projects, generating components, and managing dependencies.

3. Angular:

Modular Architecture: Angular follows a modular architecture, where functionality is divided into modules, components, services, and directives. Modules encapsulate related functionality, while components define the UI and logic for a specific part of the application. Services provide shared functionality across components, and directives enhance the behavior of HTML elements.

Angular CLI and TypeScript Integration: Angular CLI provides a command-line interface for generating components, services, modules, and other Angular artifacts. Angular projects are built using TypeScript, a superset of JavaScript that adds static typing and other advanced features to the language.

Dependency Injection: Angular’s dependency injection system allows developers to define dependencies in a central location and inject them into components, services, and other Angular artifacts. This promotes code reusability, testability, and maintainability by decoupling components from their dependencies.

RxJS and Observables: Angular leverages RxJS, a reactive programming library, to handle asynchronous operations and manage state within applications. Observables are used to represent streams of data over time, enabling developers to handle complex asynchronous scenarios with ease.

Template Syntax and Two-Way Data Binding: Angular’s template syntax allows developers to bind data and events between the component logic and the UI. Angular supports two-way data binding, where changes to the model are reflected in the view and vice versa, providing a seamless and interactive user experience.
