Don't call your self react developer until you don't know this
- React utilizes ReactDOM as the rendering engine to connect its components to the real DOM efficiently, improving performance and responsiveness.
- JSX simplifies the creation of React components by compiling into JavaScript function calls using React.createElement.
- Components in React are either functions or classes that return a description of the UI, with React managing virtual DOM nodes and real DOM updates.
- Reconciliation process in React ensures efficient updates by comparing virtual and real DOM, updating only necessary parts to enhance performance.
- React Hooks like useState are managed internally through state slots, requiring consistent order of calls within components to function correctly.
- React Fiber, introduced in React 16, revolutionized rendering by breaking down work into smaller units, enabling incremental and interruptible rendering.
- Fiber nodes in React represent elements or components as JavaScript objects with links, facilitating smart scheduling and prioritization of updates.
- React Fiber's commit phase applies DOM updates and executes effects, ensuring smooth rendering and enabling features like concurrent rendering and Suspense.
- Understanding React's internals empowers developers to write cleaner code, avoid common mistakes, and leverage the framework's performance optimizations.
- By delving into React's inner workings, developers gain insights into the design decisions that drive React's efficiency and user experience, enhancing their proficiency with the library.
