What is a RESTful API?
REST, or Representational State Transfer, is an architectural pattern that provides guidelines for creating scalable and efficient web services. It's all about communication between different software applications through a common interface. A RESTful API adheres to these principles to ensure seamless data exchange across the web. 🌍

Understanding APIs:
An API (Application Programming Interface) is a set of protocols and tools for building software and applications. It allows different systems to communicate with each other, sharing data and functionality. The beauty of an API lies in its ability to simplify complex interactions, making it easier for developers to integrate new features or services without having to build everything from scratch. 🤝

The World of RESTful APIs:
RESTful APIs are particularly powerful because they leverage the HTTP protocol, which is ubiquitous on the web. The four fundamental HTTP methods you'll encounter are GET, POST, PUT, and DELETE. These methods form the backbone of a CRUD system (Create, Read, Update, Delete), enabling you to perform various data operations through your API. 🛠️

Core HTTP Methods:

• GET: Retrieves data from a specified resource without making any changes to it.
• POST: Submits new data for processing to a specified resource, creating a new resource or updating an existing one.
• PUT: Replaces the existing data of a specified resource with an updated set of data.
• DELETE: Removes the specified resource from existence.

Course Breakdown:
In this comprehensive course, you will embark on a journey to build your very own REST API using Node.js and Express, one of the most popular server frameworks for JavaScript. Here's what you'll cover:

• 🛠️ Create a web API: Learn the fundamentals of setting up an API from scratch.
• 🚀 Build an express server: Get hands-on experience with creating a server using Express and understand how it simplifies your web application development.
• ⚙️ Create request handlers with CRUD methods: Master the art of handling different types of requests and performing CRUD operations with ease.
• 📐 Configure routing, URL paths, and return values: Discover how to design clean and efficient routing systems to organize your API endpoints.
• 🔧 Call the web API with Postman: Learn to interact with your own REST API using Postman, one of the most popular tools for API development and testing.
• ✅ Perform CRUD operations on API using Postman as API Client: Practice performing real-world operations on your API through Postman.
• 🔍 Validate data for the API: Ensure the integrity and security of your API by learning how to validate incoming data.
