[PAGE ISSUE] First steps - Building our app

[SOORAJ-SJ]

I've just started getting into Blockchain and have had some issues with the first step tutorials. 'Ropsten testnet' is now deprecated and is not available in MetaMask. I have did some research and found an alternative in 'Sepolia Testnet' network. I have also had CORS related issues in the ethers CDN.

Ropsten testnet alternative - Sepolia Testnet

Since Ropsten testnet is discontinued I have tried out Sepolia Testnet. I have also found a simple smart contract in the network called Guess (0x5aE5Ba963C2aa350D9E6Cd695e8a449975b2B5C9). The tutorial could be updated with minor modifications to the content and in the example code.

CORS error in ether's CDN.

I don't know if this was an issue caused by my side. But a quick fix i found was to use https://cdn-cors.ethers.io/lib/ethers-5.5.4.esm.min.js this CDN.
