FAQ on React JS:
- What is React JS?
- React JS is an open-source JavaScript library used for building user interfaces, primarily for single-page applications.
- How does React differ from other JavaScript frameworks like Angular or Vue?
- React is more focused on the view in the MVC model and is often considered a library rather than a full-fledged framework. Unlike Angular or Vue, it only handles the UI part and can be integrated with other libraries.
- What is JSX?
- JSX stands for JavaScript XML. It is a syntax extension for JavaScript and is used with React to describe UI elements.
- Why is React’s virtual DOM beneficial?
- The virtual DOM allows for efficient updates and rendering, as changes are first made to the virtual DOM and then the real DOM is updated selectively, improving performance.
- What are React hooks?
- Hooks are functions that allow you to “hook into” React state and lifecycle features from function components.
- How do components communicate in React?
- Components in React communicate primarily through props, but context and hooks like useContext can also be used for more global data.
- What is Redux and how does it relate to React?
- Redux is a predictable state container for JavaScript apps, often used with React to manage application state across components.
- Can React be used for mobile app development?
- Yes, with React Native, a framework derived from React, developers can create native mobile applications.
- What is a React Fragment?
- Fragments let you group a list of children without adding extra nodes to the DOM.
- Why are keys important in a list in React?
- Keys help React identify which items have changed, are added, or removed, and thus give a stable identity to elements, making the rendering process more efficient.
