NFT Collection in JavaScript

In this repository, the code written in JS is for storing and printing NFTs (Non-Fungible Tokens) for a user. The code demonstrates how to create, manage, and display an NFT collection using JavaScript. Below is a step-by-step explanation of the code.

Steps to Create and Manage NFTs

1. Create a Variable to Hold Your NFTs

creating an empty array to store our NFTs.

let nfts = [];

2. Create a Set to Store Used IDs

A Set to keep track of the IDs that have already been used to ensure each NFT has a unique ID.

let usedIds = new Set();

3. Create a Function to Generate a Unique Random ID

This function generates a random ID between 1 and 1000 and checks if it has already been used. If it has, it generates a new one until it finds a unique ID.

function generateRandomId() {
    let id;
    do {
        id = Math.floor(Math.random() * 1000) + 1; // Generate a random ID between 1 and 1000
    } while (usedIds.has(id)); // Repeat if the ID is already used
    usedIds.add(id); // Add the new unique ID to the Set
    return id;
}

4. Create a Function to Mint NFTs

This function takes in parameters to create an NFT object with metadata (title, author, publicationYear, genre) and a unique ID. It then stores this NFT in the nfts array.

function mintNFT(title, author, publicationYear, genre) {
   
    let nft = {
        id: generateRandomId(), // Assign a unique random ID
        title: title,
        author: author,
        publicationYear: publicationYear,
        genre: genre
    };
    // Adding NFT object to the array
    nfts.push(nft);
}

5. Create a Function to List All NFTs in a Tabular Format

This function lists all NFTs stored in the nfts array in a tabular format.

function listNFTs() {
    console.table(nfts);
}

6. Create a Function to Get the Total Supply of NFTs

This function returns the total number of NFTs created.

function getTotalSupply() {
    return nfts.length;
}

7. Mint Some NFTs and Display Them

Below there are some NFTs with Indian book details and then list them and print the total number of NFTs minted.

mintNFT("The God of Small Things", "Arundhati Roy", 1997, "Fiction");
mintNFT("Midnight's Children", "Salman Rushdie", 1981, "Historical Fiction");
mintNFT("The White Tiger", "Aravind Adiga", 2008, "Fiction");

listNFTs();
console.log(`Total NFTs minted: ${getTotalSupply()}`);

This project demonstrates how to manage a collection of NFTs, ensuring each one is unique and easily viewable. The code provides a basic framework for creating and displaying NFTs in a simple and organized manner.
