Full stack development involves working on both frontend (client-side) and backend (server-side) of web applications.

Frontend handles UI/UX in the browser; backend handles data, logic, authentication, and communication with databases and servers.

PUT replaces an entire resource; PATCH updates only specific fields of a resource, both using HTTP.

Common languages include HTML, CSS, JavaScript (frontend) and Java, Python, PHP, Node.js (backend).

Webpack bundles JavaScript files and assets for efficient loading, enabling modern frontend development workflows.

DevOps combines development and operations, using automation and CI/CD to streamline code deployment and infrastructure management.

Responsive design ensures websites adapt seamlessly to different screen sizes and devices for optimal user experience.

CRUD stands for Create, Read, Update, Delete – the four basic operations performed on database resources via backend.

CORS (Cross-Origin Resource Sharing) controls access between resources from different domains for secure web communication.

Node.js runs JavaScript server-side, allowing scalable, event-driven backend applications using non-blocking I/O.

Virtual DOM is a lightweight JavaScript representation of the real DOM used for efficient updates in frontend frameworks.

JWT (JSON Web Token) is a compact, URL-safe token used for securely transmitting user authentication information.

SPAs load a single HTML page and dynamically update content using JavaScript without full page reloads, improving performance.

MongoDB is NoSQL and schema-less; MySQL is relational and schema-based, using structured queries and normalized data.

async/await simplifies handling asynchronous code, making it more readable and avoiding nested .then() chains.

SQL uses structured schema and relational tables; NoSQL stores data in flexible formats like JSON, documents, key-value pairs.

MVC (Model-View-Controller) separates application logic into models (data), views (UI), and controllers (business logic).

Middleware functions process HTTP requests before reaching route handlers or after responses, enhancing functionality like auth or logging.

A promise represents a future value, handling asynchronous operations like API calls with .then() and .catch() methods.

package.json manages project dependencies, scripts, versioning, and metadata in Node.js-based full stack applications.

REST APIs allow communication between frontend and backend through standardized HTTP requests like GET, POST, PUT, DELETE.

State management handles dynamic data in components, using tools like Redux or React Context for predictable updates.

A component is a reusable piece of UI in React, defined as functions or classes returning JSX elements.

DOM (Document Object Model) represents structured HTML elements as objects manipulated by JavaScript for dynamic page content.

Hooks are functions like useState and useEffect that manage state and lifecycle features in functional components.

 APIs (Application Programming Interfaces) allow communication between the front-end and back-end, enabling data exchange and functionality integration.

Scalability ensures that applications can handle increased load by optimizing code, database queries, and utilizing load balancers.

Ensuring web accessibility means designing applications that are usable by people with disabilities, adhering to standards like WCAG.

WebSockets enable real-time communication between the client and server, essential for applications like chat apps and live updates.

 The MERN stack uses React for the front-end, while the MEAN stack utilizes Angular. Both stacks share MongoDB, Express.js, and Node.js for back-end development.

Implementing proper error handling mechanisms, such as try-catch blocks and logging, ensures that applications can gracefully handle exceptions.

Implementing SEO best practices ensures that web applications are discoverable by search engines, increasing visibility and traffic.

DevOps practices integrate development and operations, promoting continuous integration and deployment, leading to faster and more reliable releases.

 Common databases include MySQL, PostgreSQL, MongoDB, and SQLite, each serving different project requirements.

Using CSS frameworks like Bootstrap and implementing media queries ensures that web applications are responsive across various devices.

Techniques include code splitting, lazy loading, caching, and optimizing database queries to enhance application speed and efficiency.

Tools like Git and platforms like GitHub facilitate version control, allowing developers to track changes, collaborate, and manage code efficiently.

State management tools like Redux and Context API help manage application state, especially in complex React applications.

Testing ensures code reliability and functionality. Common testing methods include unit testing, integration testing, and end-to-end testing.

A RESTful API adheres to REST principles, providing a standardized way for the front-end to interact with the back-end, enhancing scalability and performance.

Cloud platforms like AWS, Azure, and Google Cloud provide scalable infrastructure, enabling Full Stack Developers to deploy and manage applications efficiently.

Key languages include HTML, CSS, JavaScript, Python, Java, and PHP. Proficiency in these languages enables developers to build comprehensive web applications.

Implementing authentication strategies like JWT (JSON Web Tokens) and OAuth ensures secure user access and data protection.

Popular frameworks include the MERN stack (MongoDB, Express.js, React, Node.js), MEAN stack (MongoDB, Express.js, Angular, Node.js), and Django with React or Vue.js.

Continuous learning through online courses, documentation, conferences, and developer communities helps stay abreast of evolving technologies.

Implementing security best practices, such as input validation, encryption, and regular updates, protects applications from vulnerabilities.

Tools like Docker allow developers to package applications and their dependencies into containers, ensuring consistency across environments.

 A Full Stack Developer handles both client-side and server-side development, working with front-end frameworks (e.g., React, Angular) and back-end technologies (e.g., Node.js, Django).

Deployment involves moving applications from development to production environments, using tools like CI/CD pipelines, Docker, and cloud services.
