React: A JavaScript library for building user interfaces, developed and maintained by Facebook. It facilitates the creation of reusable UI components.
Redux: A state management library for JavaScript applications, often used in conjunction with React. Redux helps manage the state of an application in a predictable and centralized manner.
Component: A modular, self-contained piece of code in React that encapsulates a specific functionality or UI element. Components can be reused throughout an application.
Virtual DOM: An in-memory representation of the actual DOM in React. It improves performance by allowing React to update only the parts of the DOM that have changed.
JSX: A syntax extension for JavaScript used with React to write XML-like code for creating React elements.
Props: Short for properties, props are used to pass data from one component to another in React. They are immutable and are set by the parent component.
State: An internal data storage mechanism in React components that allows them to keep track of changing information. Unlike props, state can be modified within a component.
Lifecycle Methods: Methods in a React component that are invoked at different stages of its lifecycle, such as mounting, updating, and unmounting.
React Router: A library that enables navigation and routing in React applications, allowing for the creation of Single Page Applications (SPAs).
Hooks: Functions introduced in React 16.8 that allow functional components to use state and other React features without writing a class.
Redux Store: The central hub where the state of a Redux application is stored. It is a single JavaScript object that represents the entire state tree.
Reducer: A pure function in Redux that specifies how the application's state changes in response to actions. Reducers take the current state and an action and return a new state.
Action: Plain JavaScript objects that describe changes in the application state. Actions must have a
typeproperty indicating the type of change.Dispatch: A method in Redux used to send actions to the Redux store. It is the only way to trigger a state change.
Middleware: Functions that have access to the action being dispatched and the current state in Redux. Middleware can be used for logging, asynchronous actions, and other purposes.
Immutable State: In Redux, the state should be treated as immutable, meaning it should not be directly modified. Instead, new copies of the state should be created.
Provider: A React component provided by React Redux that makes the Redux store available to the rest of the application.
Connect: A higher-order component provided by React Redux that connects a React component to the Redux store, allowing it to access the state and dispatch actions.
Thunk: A middleware for Redux that allows the action creators to return functions instead of plain actions. Thunks are often used for handling asynchronous operations.
Selectors: Functions in Redux that are used to extract specific pieces of information from the state. They help in keeping the component logic independent of the shape of the state.
Higher-Order Component (HOC): A function that takes a component and returns a new component with additional props or behavior.
Context API: A feature in React that allows data to be passed through the component tree without having to pass props manually at every level.
CSS-in-JS: A technique where styles are defined directly within JavaScript files, often used in React applications for component-specific styling.
Webpack: A popular module bundler for JavaScript applications. It is commonly used in React projects to bundle and optimize assets.
Babel: A JavaScript compiler that converts ECMAScript 2015+ code into a backward-compatible version of JavaScript for older browsers.
JSX Compiler: A tool that translates JSX code into JavaScript that browsers can understand. Babel is commonly used for this purpose in React projects.
PropTypes: A library used in React for documenting and validating the types of props that a component should receive.
React Fragment: A syntax in React used to group multiple elements without introducing an additional DOM node.
Error Boundary: A React component that catches JavaScript errors anywhere in the component tree and logs those errors.
CSS Modules: A way to locally scope CSS in React applications, preventing style conflicts between different components.
Lazy Loading: A technique where components or assets are loaded only when they are actually needed, improving the initial load time of a React application.
Code Splitting: The process of breaking down a large JavaScript bundle into smaller, more manageable chunks that can be loaded on demand.
Server-Side Rendering (SSR): A technique where a React application is rendered on the server side and the generated HTML is sent to the client, improving initial page load performance.
Client-Side Rendering (CSR): The traditional approach where a React application is rendered on the client side using JavaScript.
Immutable.js: A library that provides immutable data structures, which can be used to enforce immutability in a Redux application.
XHR Request: Stands for XMLHttpRequest, a feature in browsers that allows making HTTP requests from the client side.
JWT (JSON Web Token): A compact, URL-safe means of representing claims to be transferred between two parties, commonly used for authentication in React applications.
Firebase: A mobile and web application development platform by Google, often used with React for real-time database and authentication.
GraphQL: A query language for APIs that allows clients to request only the data they need. It is an alternative to REST and is often used with React.
PropTypes: A library used in React for documenting and validating the types of props that a component should receive.
Serverless Architecture: An architectural approach where the server is abstracted away, and developers focus on writing functions that run in response to events.
WebSocket: A communication protocol that provides full-duplex communication channels over a single, long-lived connection, often used for real-time features in React applications.
Axios: A popular JavaScript library used for making HTTP requests in React applications.
JWT (JSON Web Token): A compact, URL-safe means of representing claims to be transferred between two parties, commonly used for authentication in React applications.
GraphQL: A query language for APIs that allows clients to request only the data they need. It is an alternative to REST and is often used with React.
Storybook: An open-source tool for developing UI components in isolation, providing a visual way to test and showcase components.
Redux DevTools: A set of developer tools that help with debugging and inspecting the state and actions in a Redux application.
Jest: A JavaScript testing framework often used with React for writing unit tests and ensuring the reliability of code.
Enzyme: A JavaScript testing utility for React that makes it easier to assert, manipulate, and traverse React components' output.
CI/CD (Continuous Integration/Continuous Deployment): Practices and tools that aim to automate the process of testing and deploying code changes in a React application.
