For Loop Issue JavaScript

Question

[

  // Define the variables
  var stringIn = [];
  var finalMessage = "Thanks for participating!";
  
  // Get input from user
  stringIn[0] = prompt("Enter the first string:");
  stringIn[1] = prompt("Enter the second string:");
  stringIn[2] = prompt("Enter the third string:");
  stringIn[3] = prompt("Enter the fourth string:");
  stringIn[4] = prompt("Enter the fifth string:");
  
  // For loop and display
  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn + "\n");
  }
  
  document.write("\n" + finalMessage);

My output should be: You entered: Alpha You entered: Bravo You entered: Charlie You entered: Delta You entered: Echo

but I'm getting:

You entered: Alpha,Bravo,Charlie,Delta,Echo You entered: Alpha,Bravo,Charlie,Delta,Echo You entered: Alpha,Bravo,Charlie,Delta,Echo You entered: Alpha,Bravo,Charlie,Delta,Echo You entered: Alpha,Bravo,Charlie,Delta,Echo

I've added my code to help with my problem. FireFox Web Console shows no errors and if I had an error, I wouldn't have any output. What is wrong with this code?

If you just write + stringIn +, how's it supposed to know which element of stringIn to use? Hence, write stringIn[myCounter] to access the element at index myCounter — Klaycon

You just need to access the index of the stringIn in your iterator.

stringIn[myCounter]

  // Define the variables
  var stringIn = [];
  var finalMessage = "Thanks for participating!";
  
  // Get input from user
  stringIn[0] = prompt("Enter the first string:");
  stringIn[1] = prompt("Enter the second string:");
  stringIn[2] = prompt("Enter the third string:");
  stringIn[3] = prompt("Enter the fourth string:");
  stringIn[4] = prompt("Enter the fifth string:");
  
  // For loop and display
  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn[myCounter] + "\n");
  }
  
  document.write("\n" + finalMessage);

Should be

  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn[myCounter] + "\n");
  }

Less duplicates & array extras forEach

const stringsNumber = ['first', 'second', 'third', 'fourth', 'fifth'];
let greetingText = 'Hello, and Welcome to my survey!\n\n';

stringsNumber.forEach(string => {
  const promptValue = prompt(`Enter the ${string} string:`);
  greetingText += `You entered: \"${promptValue}\" to be the ${string} string.\n`;
})

greetingText += '\nThanks for participating!';

document.write(greetingText);

body {
  margin: 0;
  white-space: pre-line;
}
