//1.function called getComputerChoice
|
||
//that will randomly return either ‘Rock’, ‘Paper’ or ‘Scissors’.
|
||
|
||
//2.function that plays a single round of Rock Paper Scissors.
|
||
//The function should take two parameters - the playerSelection and computerSelection -
|
||
//and then return a string that declares the winner of the round like so:
|
||
//"You Lose! Paper beats Rock"
|
||
//Make your function’s playerSelection parameter case-insensitive
|
||
//(so users can input rock, ROCK, RocK or any other variation).
|
||
|
||
//3.Important note: you want to return the results of this function call, not console.log() them.
|
||
//You’re going to use what you return later on,
|
||
//so let’s test this function by using console.log to see the results:
|
||
|
||
//4.Write a NEW function called game().
|
||
//Call the playRound function inside of this one to play a 5 round game
|
||
//that keeps score and reports a winner or loser at the end.
|
||
//At this point you should be using console.log() to display
|
||
//the results of each round and the winner at the end.
|
||
//Use prompt() to get input from the user. Read the docs here if you need to.
|
||
//Feel free to re-work your previous functions if you need to.
|
||
//Specifically, you might want to change the return value to something more useful.
|
||
//Feel free to create more “helper” functions if you think it would be useful.
