We’re going to make a simple implementation of grade-school classic “rock paper scissors”. If you don’t know what that is check the Wikipedia article or this ridiculous step-by-step. For the moment we’re just going to play the game from the browser console, but we will revisit it and add a front end later so don’t forget to keep the code on GitHub! You might notice some ‘view in browser’ links in the student solutions - this is coming in a later lesson. When you get there don’t forget to come back and add your link!
computerPlay
that will randomly return either ‘Rock’, ‘Paper’ or ‘Scissors’. We’ll use this function in the game to make the computer’s play.playerSelection
and computerSelection
- and then return a string that declares the winner of the round like so: "You Lose! Paper beats Rock"

, ROCK
, RocK
or any other variation)Important note: you want to return
the results of this function call, not console.log()
them. To test this function console.log the results:
function playRound(playerSelection, computerSelection) {
// your code here!
}
const playerSelection = "rock";
const computerSelection = computerPlay();
console.log(playRound(playerSelection, computerSelection));
game()
. Use the previous function inside of this one to play a 5 round game that keeps score and reports a winner or loser at the end.
playRound
function 5 times in a row. Loops are covered in the next lesson.console.log()
to display the results of each round and the winner at the end.prompt()
to get input from the user. Read the docs here if you need to.5-6 months
