In this quick session, I will talk about how to build a fast, efficient, and scalable REST API using Express.js, one of the most popular Node.js frameworks. I'll cover the core concepts of RESTful architecture, walk through setting up basic API routes, differences between REST APIs and Local APIs and demonstrate how to handle common HTTP requests (GET, POST, PUT, DELETE). This talk will provide the audience with the essential knowledge to create APIs that power modern web applications. By the end, the audience have a solid foundation for building and expanding their own APIs using Express.

I'll cover the below mentioned points:

1. Introduction to REST APIs and Backend Development
2. Differences between REST APIs vs Local APIs
3. Basics of HTTP and HTTP requests
4. Building a basic REST API with Express.js
