MERN Stack Developer Program

JavaScript Essentials & ES6+ cover the core concepts needed to build modern web applications. This includes variables, functions, loops, and asynchronous programming. ES6+ introduces features like arrow functions, classes, modules, and promises. Together, they enable cleaner, more efficient, and maintainable JavaScript code.

Building REST APIs with Express & Node involves creating scalable backend services using Node.js and the Express framework. Express simplifies routing, middleware handling, and request–response management. REST APIs expose endpoints for CRUD operations using standard HTTP methods. This approach enables secure, fast, and maintainable server-side application development.

React Fundamentals & Hooks focus on building dynamic user interfaces using reusable components. React fundamentals include JSX, components, props, and state management. Hooks like useState, useEffect, and useContext allow managing state and side effects in functional components. This approach makes React code simpler, cleaner, and easier to maintain.

State Management with Redux / Context helps manage and share application state across components. Redux provides a centralized store with predictable state changes using actions and reducers. React Context offers a simpler way to pass global data without prop drilling. Both approaches improve scalability, consistency, and maintainability of React applications.

MongoDB Aggregations & Performance focus on optimizing database queries and data processing. Aggregation pipelines allow filtering, sorting, and transforming data efficiently. Indexing strategies improve query speed, while schema design ensures scalability. These practices are essential for building fast, reliable, and maintainable applications.

Deployment to Cloud (Render/Heroku/AWS) involves packaging and hosting MERN applications on cloud platforms. Containerisation with Docker ensures consistency across environments. CI/CD pipelines automate testing and deployment. Environment variables manage configuration, while scaling strategies ensure performance. These practices enable reliable, secure, and efficient application delivery.
