Make the following variables (all of them should be OUTSIDE OF EVERY FUNCTION ON TOP OF MAIN.JS), along with the variables I left for you containing images: computerNumber, start it with -1 or any other numberdefine a function and attach it to each of your buttons (and/or to the user hitting the enter key). Call it takeTurn. This function should take a parameter. 1 for rock, 2 for paper, 3 for scissors:each button should have a function call with a different number passed in as a parameter based on how the function should expect numbersIn the function, reassign computerNumber to a random number between 1 and 3 (use randomInt() )Also put two alerts, one to show the user's number (representing which button they pushed) and one to show the computer's random numberYou are done when the alert in the function works correctly

Solution

Sure, here is a step-by-step guide on how to implement this in JavaScript:

  1. First, declare the variable computerNumber at the top of your main.js file and initialize it with -1 or any other number. This should be outside of any function:
let computerNumber = -1;
  1. Next, define a function called takeTurn. This function should take a parameter which will be 1 for rock, 2 for paper, and 3 for scissors:
function takeTurn(userNumber) {
    // function body will go here
}
  1. Inside the takeTurn function, reassign computerNumber to a random number between 1 and 3. You can use the Math.floor(Math.random() * 3) + 1 to generate a random number in this range:
function takeTurn(userNumber) {
    computerNumber = Math.floor(Math.random() * 3) + 1;
    // rest of the function body will go here
}
  1. Still inside the takeTurn function, add two alert statements. One should show the user's number (which is the parameter of the function) and the other should show the computer's random number:
function takeTurn(userNumber) {
    computerNumber = Math.floor(Math.random() * 3) + 1;
    alert("User's number: " + userNumber);
    alert("Computer's number: " + computerNumber);
}
  1. Finally, attach this function to each of your buttons. The function call should have a different number passed in as a parameter based on the button. For example, if you have buttons with ids rock, paper, and scissors, you can do this:
document.getElementById('rock').onclick = function() { takeTurn(1); };
document.getElementById('paper').onclick = function() { takeTurn(2); };
document.getElementById('scissors').onclick = function() { takeTurn(3); };

This will call the takeTurn function with the appropriate parameter when each button is clicked.
