Now it is time to update the scores and the round results message.
Create a showResults function with a parameter called userOption.
Inside your showResults function, the roundResultsMsg should be updated with the result of the round.
Then, the playerScoreSpanElement and computerScoreSpanElement should also be updated to show the updated scores of the player and computer.
Remember, that the order matters here. You will need to first update the roundResultsMsg, then the playerScoreSpanElement, and finally the computerScoreSpanElement because the roundResultsMsg will be used to determine the scores.
You should have a function called showResults.
assert.isFunction(showResults);
Your showResults function should have a parameter called userOption.
assert.match(code, /showResults\s*(?:=\s*)?(?:\(\s*)?userOption(?:\s*\))?\s*/);
Your showResults function should update the roundResultsMsg with the result of the round.
const possibleResults = [
"Player wins! Rock beats Scissors",
"Player wins! Scissors beats Paper",
"Player wins! Paper beats Rock",
"Computer wins! Paper beats Rock",
"Computer wins! Scissors beats Paper",
"Computer wins! Rock beats Scissors",
"It's a tie! Both chose Rock",
"It's a tie! Both chose Scissors",
"It's a tie! Both chose Paper"
];
showResults("Rock");
assert.include(possibleResults, roundResultsMsg.innerText.replace(/\//g, "'"));
Your showResults function should update the computerScoreSpanElement to show the updated score of the computer.
computerScore = 0;
const oldRandomResult = getRandomComputerResult;
getRandomComputerResult = () => "Rock";
showResults("Scissors");
assert.equal(computerScoreSpanElement.innerText, "1");
getRandomComputerResult = oldRandomResult;
Your showResults function should update the playerScoreSpanElement to show the updated score of the player.
playerScore = 0;
const oldRandomResult = getRandomComputerResult;
getRandomComputerResult = () => "Scissors";
showResults("Rock");
assert.equal(playerScoreSpanElement.innerText, "1");
getRandomComputerResult = oldRandomResult;

<p>You will be playing against the computer.</p>
<p>You can choose between Rock, Paper, and Scissors.</p>
<p>The first one to three points wins.</p>
<p>Here are the rules to getting a point in the game:</p>

<li>Rock beats Scissors</li>

If the player and computer choose the same option (e.g., Paper and
