lesson 5 updateFavoriteNumber

[LT-TMC]

Hello fellow Students, I have a question regarding the updateFavoriteNumber

I think it's going to be a simple one and just a silly noob question on my part, but once updating FavoriteNuber I notice that in Ganache that there is a contract call and contract creation every time I updateFavoriteNumber is this normal? I'm thinking not because the gas price will be insane.

const ethers = require("ethers"); 
const fs = require("fs-extra");

async function main() {

  const provider = new ethers.providers.JsonRpcProvider(
    "i have deleted the wallet address just out of habit "
  );
  const wallet = new ethers.Wallet(
    "", // its a big no no to put private keys in code
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy(); // stop here wait for contract to deploy
  await contract.deployTransaction.wait(1); // <-- this goes down


  const currentFavoriteNumber = await contract.retrieve();
  console.log(`Current Favorite Number: ${currentFavoriteNumber.toString()}`);
  const transactionResponse = await contract.store("8");
  const transactionReceipt = await transactionResponse.wait(1);
  const updatedFavoriteNumber = await contract.retrieve();
  console.log(`Updated favorite number is: ${updatedFavoriteNumber}`);

 
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

@Themorningcormorant Actually here you are running the whole script that includes the deploy part, later you will learn about deploying scripts and running scripts separately.
