Hi there, i’ve already completed this task with some help from other forum posts, but im trying to find out why the value userOption isn’t defined anywhere in the code but it becomes relied on for the parameter and for the getRoundResults function. I would appreicate help

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

const playerScoreSpanElement = document.getElementById("player-score");
const computerScoreSpanElement = document.getElementById("computer-score");
const roundResultsMsg = document.getElementById("results-msg");

function showResults(userOption) {
  playerScoreSpanElement.innerText = playerScore;
  computerScoreSpanElement.innerText = computerScore;
  roundResultsMsg.innerText = getRoundResults;
};

showResults("Rock");

// User Editable Region

Hi @graemec13

userOption is a parameter for the showResults functions.

It acts as placeholder code.

You call the showResults function with an argument.

Wherever userOption is mentioned in the function, it refers back to the argument.

Happy coding
