Rock Paper Scissors
Let's play! You have to return which player won! In case of a draw return Draw!.

Examples:

rps('scissors','paper') // Player 1 won!
rps('scissors','rock') // Player 2 won!
rps('paper','paper') // Draw!
*/

// First Attempt - Feb 2019

const rps = (p1, p2) => {
	if (p1 == p2) return 'Draw!';

	if (p1 == 'rock') {
		if (p2 == 'scissors') return 'Player 1 won!';
		if (p2 == 'paper') return 'Player 2 won!';
	}
	if (p1 == 'scissors') {
		if (p2 == 'paper') return 'Player 1 won!';
		if (p2 == 'rock') return 'Player 2 won!';
	}
	if (p1 == 'paper') {
		if (p2 == 'scissors') return 'Player 2 won!';
		if (p2 == 'rock') return 'Player 1 won!';
	}
};

// Second Attempt - Feb 2020

const rps = (p1, p2) => {
	if (p1 === p2) return 'Draw!';

	if (p1 === 'scissors') {
		if (p2 === 'rock') {
			return 'Player 2 won!';
		}
		if (p2 === 'paper') {
			return 'Player 1 won!';
		}
	}

	if (p1 === 'paper') {
		if (p2 === 'rock') {
			return 'Player 1 won!';
		}
		if (p2 === 'scissors') {
			return 'Player 2 won!';
		}
	}

	if (p1 === 'rock') {
		if (p2 === 'paper') {
			return 'Player 2 won!';
		}
		if (p2 === 'scissors') {
			return 'Player 1 won!';
		}
