Reactivity Model

react: React uses a virtual DOM to optimize updates. When the state of a component changes, React calculates the minimal number of changes required to update the actual DOM, resulting in efficient rendering and improved performance.
vue: Vue combines the best of both worlds with a reactive data-binding system and a virtual DOM. It allows for efficient updates while providing a simple and intuitive API for managing state.
@angular/core: Angular employs a complex change detection mechanism that tracks changes in the application state and updates the UI accordingly. It uses zones to manage asynchronous operations and ensures that the UI reflects the latest state, but this can lead to performance issues if not managed properly.
svelte: Svelte introduces a unique reactivity model where the compiler converts declarative components into imperative code at build time. This means that there is no virtual DOM, and updates are made directly to the DOM, leading to faster performance and smaller bundle sizes.

Learning Curve

react: React is relatively easy to learn, especially for developers familiar with JavaScript. Its component-based architecture and focus on reusable components make it accessible, though mastering advanced concepts like hooks and context can take time.
vue: Vue offers a gentle learning curve with its straightforward API and documentation. It allows developers to incrementally adopt its features, making it easy to integrate into existing projects.
@angular/core: Angular has a steeper learning curve due to its extensive features and concepts such as dependency injection, decorators, and RxJS for reactive programming. It requires a solid understanding of TypeScript and its architecture.
svelte: Svelte is designed to be beginner-friendly with a simple syntax and fewer concepts to grasp. Developers can quickly start building applications without the overhead of a complex framework, making it an excellent choice for newcomers.

Community and Ecosystem

react: React boasts one of the largest ecosystems with a vast array of libraries, tools, and community support. Its flexibility allows developers to choose from many options for state management, routing, and more.
vue: Vue has a vibrant community and a rich ecosystem of plugins and tools. It is well-documented, and its community-driven approach fosters a wide range of resources and libraries.
@angular/core: Angular has a strong community backed by Google, providing extensive resources, libraries, and tools. However, its ecosystem can be somewhat opinionated, which may limit flexibility in choosing third-party libraries.
svelte: Svelte's community is growing rapidly, and while it may not have as many resources as React or Angular, it is known for its enthusiastic and supportive community. The ecosystem is expanding with libraries and tools tailored for Svelte.

Performance

react: React is optimized for performance through its virtual DOM and efficient reconciliation process. However, developers must be mindful of unnecessary re-renders and can use techniques like memoization to further improve performance.
vue: Vue provides good performance with its virtual DOM and optimized reactivity system. It allows developers to fine-tune performance through features like async components and lazy loading.
@angular/core: Angular's performance can be impacted by its change detection strategy, especially in large applications with many components. Developers need to optimize their applications using techniques like OnPush change detection and lazy loading to enhance performance.
svelte: Svelte is known for its excellent performance due to its compile-time optimization. It generates highly efficient JavaScript code that minimizes runtime overhead, leading to faster applications with smaller bundle sizes.

Extensibility

react: React is highly extensible, allowing developers to integrate a wide range of libraries and tools. Its component-based architecture encourages the creation of reusable components that can be easily shared across projects.
vue: Vue's extensibility is one of its strengths, with a flexible architecture that allows for easy integration of plugins and libraries. Developers can create custom directives and mixins to extend functionality.
@angular/core: Angular's extensibility is facilitated through its modular architecture, allowing developers to create reusable components and services. However, its opinionated structure can make it challenging to integrate with non-Angular libraries.
svelte: Svelte is extensible through its simple syntax and component model, allowing developers to create custom components and integrate them into applications. However, its ecosystem is still developing compared to more established frameworks.

react

React is a JavaScript library for creating user interfaces.

The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.

Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.

Usage

import { useState } from 'react'; import { createRoot } from 'react-dom/client'; function Counter() { const [count, setCount] = useState(0); return ( <> <h1>{count}</h1> <button onClick={() => setCount(count + 1)}> Increment </button> </> ); } const root = createRoot(document.getElementById('root')); root.render(<App />);
