Study Notes
React and React Native Overview
- React uses 1-way data binding, unlike Angular, and employs a Virtual DOM for efficient updates.
- JSX allows easy mixing of HTML and JS, and React has a strong developer community and useful dev tools.
- Components are the building blocks of React applications, allowing for the UI to be split into reusable pieces.
- React has functional/stateless and class/stateful components, with the latter maintaining its own state and lifecycle.
- State in React is a JavaScript object containing component data, accessed via this.state and updated using setState().
- React Native is a framework for building native, cross-platform mobile apps using JavaScript and React.
- React Native implements a strict subset of CSS and is used by startups for its cost-effective development.
- React and React Native differ in that React is for building dynamic web interfaces, while React Native is for native mobile apps.
- React follows a unidirectional data flow and offers more flexibility in choosing additional libraries or tools.
- Angular, on the other hand, is a full-fledged MVC framework developed by Google, built on TypeScript.
- Angular supports two-way data binding, uses RxJS for asynchronous tasks, and has a steeper learning curve compared to React.
- Both React and Angular are popular for building SPAs, focus on high performance, but differ in flexibility and tooling.
