Frontend Frameworks Interview Q&A โ Part 1 ๐๐ผ
1๏ธโฃ What are props in React?
Answer: Props (short for properties) are used to pass data from parent to child components. They are read-only and help make components reusable.
2๏ธโฃ What is state in React?
Answer: State is a built-in object used to store dynamic data that affects how the component renders. Unlike props, state can be changed within the component.
3๏ธโฃ What are React hooks?
Answer: Hooks like useState, useEffect, and useContext let you use state and lifecycle features in functional components without writing class components.
4๏ธโฃ What are directives in Vue.js?
Answer: Directives are special tokens in Vue templates that apply reactive behavior to the DOM. Examples include v-if, v-for, and v-bind.
5๏ธโฃ What are computed properties in Vue?
Answer: Computed properties are cached based on their dependencies and only re-evaluate when those dependencies change โ great for performance and cleaner templates.
6๏ธโฃ What is a component in Angular?
Answer: A component is the basic building block of Angular apps. It includes a template, class, and metadata that define its behavior and appearance.
7๏ธโฃ What are services in Angular?
Answer: Services are used to share data and logic across components. Theyโre typically injected using Angularโs dependency injection system.
8๏ธโฃ What is conditional rendering?
Answer: Conditional rendering means showing or hiding UI elements based on conditions. In React, you can use ternary operators or logical && to do this.
9๏ธโฃ What is the component lifecycle in React?
Answer: Lifecycle methods like componentDidMount, componentDidUpdate, and componentWillUnmount manage side effects and updates in class components. In functional components, use useEffect.
๐ How do frameworks improve frontend development?
Answer: They offer structure, reusable components, state management, and better performance โ making development faster, scalable, and more maintainable.

Frontend Frameworks Interview Q&A โ Part 2 ๐๐ผ
1๏ธโฃ What is Virtual DOM in React?
Answer:
The Virtual DOM is a lightweight copy of the real DOM. React updates it first, calculates the difference (diffing), and then efficiently updates only what changed in the actual DOM.
2๏ธโฃ Explain data binding in Angular.
Answer:
Angular supports one-way, two-way ([(ngModel)]), and event binding to sync data between the component and the view.
3๏ธโฃ What is JSX in React?
Answer:
JSX stands for JavaScript XML. It allows you to write HTML-like syntax inside JavaScript, which is compiled to Reactโs createElement() calls.
4๏ธโฃ What are slots in Vue.js?
Answer:
Slots allow you to pass template content from parent to child components, making components more flexible and reusable.
5๏ธโฃ What is lazy loading in Angular or React?
Answer:
Lazy loading is a performance optimization technique that loads components or modules only when needed, reducing initial load time.
6๏ธโฃ What are fragments in React?
Answer:
<React.Fragment> or <> lets you group multiple elements without adding extra nodes to the DOM.
7๏ธโฃ How do you lift state up in React?
Answer:
By moving the shared state to the closest common ancestor of the components that need it, and passing it down via props.
8๏ธโฃ What is a watch property in Vue?
Answer:
watch allows you to perform actions when data changes โ useful for async operations or side effects.
9๏ธโฃ What is dependency injection in Angular?
Answer:
A design pattern where Angular provides objects (like services) to components, reducing tight coupling and improving testability.
๐ What is server-side rendering (SSR)?
Answer:
SSR renders pages on the server, not the browser. It improves SEO and load times. Examples: Next.js (React), Nuxt.js (Vue), Angular Universal.

Backend Basics Interview Questions โ Part 1 (Node.js) ๐ง ๐ป
๐ 1. What is Node.js?
A: Node.js is a runtime environment that lets you run JavaScript on the server side. It uses Googleโs V8 engine and is designed for building scalable network applications.
๐ 2. How is Node.js different from traditional server-side platforms?
A: Unlike PHP or Java, Node.js is event-driven and non-blocking. This makes it lightweight and efficient for I/O-heavy operations like APIs and real-time apps.
๐ 3. What is the role of the package.json file?
A: It stores metadata about your project (name, version, scripts) and dependencies. Itโs essential for managing and sharing Node.js projects.
๐ 4. What are CommonJS modules in Node.js?
A: Node uses CommonJS to handle modules. You use require() to import and module.exports to export code between files.
๐ 5. What is the Event Loop in Node.js?
A: It allows Node.js to handle many connections asynchronously without blocking. Itโs the heart of Nodeโs non-blocking architecture.
๐ 6. What is middleware in Node.js (Express)?
A: Middleware functions process requests before sending a response. They can be used for logging, auth, validation, etc.
๐ 7. What is the difference between process.nextTick(), setTimeout(), and setImmediate()?
A:
โฆ process.nextTick() runs after the current operation, before the next event loop.
โฆ setTimeout() runs after a minimum delay.
โฆ setImmediate() runs on the next cycle of the event loop.
๐ 8. What is a callback function in Node.js?
A: A function passed as an argument to another function, executed after an async task finishes. Itโs the core of async programming in Node.
๐ 9. What are Streams in Node.js?
A: Streams let you read/write data piece-by-piece (chunks), great for handling large files. Types: Readable, Writable, Duplex, Transform.
๐ 10. What is the difference between require and import?
A:
โฆ require is CommonJS (used in Node.js by default).
โฆ import is ES6 module syntax (used with "type": "module" in package.json).
