Problem:

A smart contract has recorded the winner of the ETHSingapore hackathon. Let's write a function that reveals the winner, but first, we need to validate the contract!

Your code:

function revealWinner(signature, contract) {
    const isValid = signature === "0xETHSingapore";
    const winner = contract.winner || "No winner yet";
    return isValid ? `The winner is... ${winner}!` : "Invalid contract. Try again.";
  }
  const contract = { winner: "decenTRUST" };
  const signature = "0xETHSingapore";
  console.log(revealWinner(signature, contract)); // Who will win? 🏆

Console Output:

The winner is... decenTRUST!
