With the deployment script in place, you can now deploy your contract to a local blockchain or a testnet.

• Start a local Ethereum node using Hardhat:

• Loops can be costly, especially if they iterate over large datasets. Limit the number of iterations or consider splitting loops into multiple transactions if possible.
• Example: Avoid looping over large arrays or mappings within a single transaction.

4. Use Efficient Data Structures

You’ll notice that calling the set function will require gas (a small amount of Ether) to execute, whereas calling the get function is free as it’s a view function.

Writing smart contracts requires attention to detail, especially when it comes to security and efficiency. Here are some best practices:
