This course will guide you through JavaScript programming essentials by leveraging your existing Python knowledge. It highlights the similarities and differences between JavaScript and Python and covers program structure, built-in data types, variables, operators, arithmetic expressions, user-defined functions, and libraries.

You’ll dive into OOP concepts on classes and objects, control flow statements, and collections (arrays, lists, maps) alongside loops. You’ll also explore commonly used libraries in JavaScript. In the culminating project, you’ll apply your skills by developing a classic Rock Paper Scissors game where one player is the computer. 

After completing the course, you’ll have a comprehensive understanding of JavaScript, enabling you to transition smoothly from Python while building robust, real-world applications.

JavaScript for Python Programmers

// Function to display game instructions
function displayInstructions(){
    console.log('Welcome to Rock Paper Scissors.\n');
    console.log('The rules are simple:');
    console.log('1. Rock beats scissors');
    console.log('2. Scissors beat paper');
    console.log('3. Paper beats rock');
}

// Function to ask for the number of rounds
function getRounds(){
  let rounds;
  do {
    rounds = prompt('How many rounds would you like to play? \nRounds: ');
    rounds = parseInt(rounds);
    if (isNaN(rounds) || rounds <= 0) {
      console.log('Please enter a valid positive integer for rounds.');
    }
  } while (isNaN(rounds) || rounds <= 0);
  return rounds;
}

// Function to get the player's choice
function getPlayerChoice(){
  const validChoices = ['rock', 'paper', 'scissors'];
  let playerChoice;
  do {
    playerChoice = prompt('Please enter rock, paper, or scissors. \nChoice: ').toLowerCase();
    if (!validChoices.includes(playerChoice)) {
      console.log('Invalid choice. Please enter either rock, paper, or scissors.');
    }
  } while (!validChoices.includes(playerChoice));
  return playerChoice;
}

// Function to contain the flow of the whole program
function main() {
    displayInstructions();
    const rounds = getRounds();
    const playerChoice = getPlayerChoice();
}


In this task, we'll create a function to get a move from the computer. 

# What’s next?

We’ll use the `choice` function in JavaScript’s `random` library to choose one of the three options and return that option as the computer’s choice.
