  What is Amazon Nova Act AI? Okay so, let me tell you about something super cool Amazon made. It's called Nova Act , and it's like a super smart robot brain that can use the internet just like we do! You know how we open websites, click stuff, type in boxes, and buy things online? Nova Act can do all that ... by itself! 1. It’s an AI Agent for Browsing the Internet So this Nova Act thing is like a robot helper that knows how to use a browser (like Chrome or Safari). It can go to websites, click buttons, fill forms, buy stuff, and even follow hard instructions without us telling it every little thing. Like imagine you said, "Hey Nova, go buy me a red t-shirt from Amazon." And guess what? It actually can go and do it all by itself! How crazy is that! 2. It Works on Its Own! One of the coolest thing about Nova Act is, once you give it a job, you don’t have to sit and watch it or tell it every step. It just knows what to do next, and it finish the task for you. Li...

How to create a Full-Stack Billing System with JavaScript, Node.js, Express, MySQL, and Semantic UI (1.0)

About the EJS Structure

 This index.ejs template is designed for a billing system's admin dashboard. It features a responsive vertical navigation bar and uses multiple card components to display important sales and inventory metrics such as total sales, stock, and orders. The template is styled using a combination of Bootstrap, Semantic UI, and custom CSS to create a clean, functional layout for managing the system's backend.

 🌐 What Is an API? (Like… Really) API stands for Application Programming Interface. Think of an API like a waiter in a restaurant . You (the customer) ask for food, the waiter takes your order , and then brings you the food from the kitchen. You don’t go into the kitchen yourself — you just tell the waiter. Same with computers! One app asks for info (like the weather), the API is the waiter , and it gets that info from another app and brings it back. That’s it! 🤔 Why Do We Need APIs? APIs help apps talk to each other Without APIs, apps wouldn’t know how to share or ask for stuff. Like... imagine your phone couldn’t get weather updates from the internet. That’d be sad, right? APIs save time for programmers Instead of building everything from scratch, developers use APIs to grab ready-made features. It’s like using Legos instead of carving wood blocks every time. They make teamwork easier Apps, websites, games — they all use APIs to get along better 🍔 A Restaurant Ex...
