Here's a link to a JS adaptation of a rock-paper-scissors game someone wrote in C.
It's pretty simple, but I'm proud of it.

Ehh, I'd like to point out that Java and JavaScript aren't related. They're completely different languages.

that's very true. They have completely different syntax and are used for completely different things. @liamdadude has given more information as to their differences below this post

I've already learned JavaScript, but I need to brush up on it considerably (along with HTML and CSS).

I'm considering learning Java for USACO, but C++ is tempting me more

It's true! For starters, Java is designed for lower level actions, like communicating with hardware, and javascript is mostly for web. Also JavaScript is a scripting language, unlike java, which is a programming language. Javascript syntax is more relaxed than Java syntax. Also, Java applications can be standalone and support Multithreading, and uses more memory (RAM) then javascript.

thanks for reading my rant lol

What are the best resources to learn javascript? Books, websites etc. I would also like to learn multiple languages after that: Python, Java, CSS, C++, C

I use Codecademy and Coursera for all of these languages. KhanAcademy has a nice HTML/CSS course, which also teaches JavaScript. Harvard's CS50 is a good place to learn C and a little bit of Python.

I don't know much in the way of books, but there's a big, very informative Python book I have somewhere. I'll have to check its name

Anyways, cool that this topic is here. I know a tiny bit but not much, but I'm still trying to learn

(I do know that java ≠ javascript and I think node.js is not a language in its own right)

bump? is that allowed?

Basic rock paper scissors. Or in plain javascript,

{
let gameOptions = ['rock', 'paper', 'scissors'];
let playerTimesWon = 0;
alert('We\'re gonna play Rock Paper Scissors. If you want to quit at any time just enter \'quit\'. :-)');
function winStatus(playerChoice, opponentChoice) {
  if (playerChoice == 'rock') {
    if (opponentChoice == 'rock') {
      return 'tied';
    } else if (opponentChoice == 'paper') {
      return 'lost';
    } else { return 'won'; }
  } else if (playerChoice == 'paper') {
    if (opponentChoice == 'rock') {
      return 'won';
    } else if (opponentChoice == 'paper') {
      return 'tied';
    } else { return 'lost'; }
  } else {
    if (opponentChoice == 'rock') {
      return 'lost';
    } else if (opponentChoice == 'paper') {
      return 'won';
    } else { return 'tied'; }
  }
}
function rockPaperScissors() {
  let i = prompt('How many times do you want to play?');
  let computerChoice;
  let myChoice;
  for (let j = 1; j <= i; j++) {
    myChoice = prompt('What is your choice?').toLowerCase();
    if (myChoice == 'quit') {
      break;
    }
    computerChoice = gameOptions[Math.floor(Math.random() * 3)];
    if (winStatus(myChoice, computerChoice) == 'won') {
      playerTimesWon++;
    }
    alert('The computer chose ' + computerChoice + '\nso you have ' + winStatus(myChoice, computerChoice) + '!! \nYou have won ' + playerTimesWon + ' times, and played ' + j + ' times.');
  }
}
rockPaperScissors();
alert('Thanks for playing, hope you had a great time! ;)');
}

(Not that it's good code but it works

) (Can someone help me make it so I'm not using brute force to determine if you won or not)
Oh, and recent edit, I included everything in a block so the console doesn't throw a "redeclaration of let variable" error, maybe I should just use var, idk
Another edit I misplaced the curly brackets XD
