1️⃣ Switch Statement
Finds the matching value of an expression and executes the code block associated with the matching value.
2️⃣ Ternary Operator
Checks a condition and executes the first expression if the condition is true. Otherwise it runs the second expression.
3️⃣ Jump / Dispatch Table
Stores value-function pairs in an object to quickly fetch and run a function based on a value (which is treated as an object key).
4️⃣ Dynamic Dispatch
This pattern involves selecting which polymorphic method to call based on an object’s type.

Node.js Learning Roadmap: From Basics to Advanced
1. Getting Started with Node.js
Introduction to Node.js: What is Node.js and why use it? Difference between Node.js and browser JavaScript.
Setup: Install Node.js and npm. Run a simple JavaScript file using Node.js.
2. Core Concepts
Modules: Built-in modules (fs, path, os, http). Create custom modules. Import/Export using CommonJS and ES modules.
Event Loop: Understand how Node.js handles asynchronous tasks.
Package Management: Manage dependencies with npm or yarn. Semantic versioning and package.json file.
3. Building a Server
Basic Server Setup: Create a simple HTTP server using http module.
Express.js Framework: Introduction to Express. Routing, middleware, and request handling. Serve static files.
4. Asynchronous Programming
Callbacks and Promises: Handle async operations.
Async/Await: Write cleaner asynchronous code.
Error Handling: Use try-catch blocks. Handle errors in middleware.
5. Working with Databases
Relational Databases: Connect to MySQL or PostgreSQL using libraries like Sequelize or Knex.js.
NoSQL Databases: Use MongoDB with Mongoose.
CRUD Operations: Implement Create, Read, Update, Delete.
6. APIs with Node.js
RESTful APIs: Build APIs using Express. Learn about routing, query parameters, and request payloads.
Authentication: Implement JWT (JSON Web Tokens) and OAuth.
GraphQL APIs: Build a GraphQL server using Apollo or Express-GraphQL.
7. Advanced Concepts
File Handling: Read and write files using fs module. Stream data for large files.
Real-Time Communication: Implement WebSockets using libraries like Socket.IO.
Performance Optimization: Use clustering and load balancing. Optimize middleware execution.
Security: Prevent common vulnerabilities (e.g., XSS, CSRF, SQL Injection). Use Helmet.js for securing HTTP headers.
8. Testing Node.js Applications
Unit testing with Mocha/Chai or Jest.
Mocking APIs using tools like Sinon.js.
9. Build Projects
Beginner: Basic HTTP server, File uploader.
Intermediate: REST API for a blog or e-commerce app.
Advanced: Real-time chat app, Task Scheduler.
Deploy on platforms like Heroku, Vercel, or AWS.
