How do I go about showing every character on a separate line using a for loop?

Question

How do I go about showing every character on a separate line using a for loop?

var input = prompt("What is Lance attempting to convey?"); 
//user enters any text

for (var i = 0; i <= input.length; i++)
{
    var output = input.charAt(i);

    if (output == "e" || output == "o" || output == "a" || output == "u")
    {
        output = "i";
    }
    else if (output != "e")
    {
        output = output;
    }
    console.log(output);
}

The current result I have when the user inputs "hello"


h
i
l
l
i

How can I display each character on a separate line.

One way to filter out specific characters in a text is by creating a list and combining the desired characters:

  var userInput = prompt("Enter your message"); 
  //user inputs any text
  var charList = [];

  for (var i = 0; i <= userInput.length; i++) {

    var character = userInput.charAt(i);

    if (character == "e" || character == "o" || character == "a" || character == "u") {
      charList.push("i");
    }else if (character != "e") {
      charList.push(character);
    }
  }

  console.log(charList.join(''));

Here are some different methods for comparison:

One approach is using a series of if statements, with a more compact syntax utilizing a for loop.

var text = prompt("Enter Lance's message"); 
//user inputs any text

var result = "";
for (var i in text) {
    var ch = text.charAt(i);
    if (ch == "e" || ch == "o" || ch == "a" || ch == "u") {
        result = result + "i";        
    } else {
        result = result + ch;        
    }
}
console.log(result);

Another method is using a switch statement

var text = prompt("Enter Lance's message"); 
//user inputs any text

var result = "";
for (var i in text) {
    var ch = text.charAt(i);
    switch (ch) {
        case "e": case "o": case "a": case "u":
            result = result + "i"
            break;
        default:
            result = result + ch;
            break;
    }
}
console.log(result)

Lastly, you can use regular expressions and a ternary operator along with the += operator to append values to a string

var text = prompt("Enter Lance's message"); 
//user inputs any text

var result = '';

for (var i in text) {
    result += function(ch) {
        return ch.match(/[eoau]/) ? "i" : ch
    }(text.charAt(i));
}
console.log(result);

Best of luck with your learning endeavors!

It seems like your goal is to achieve a specific outcome without using array join and push operations as requested. I've also corrected the <= in the for loop and removed the unnecessary else if, leaving just else.

var text = prompt("Please input what Lance is attempting to communicate");
// The user enters any text

var collect = '';

for (var i = 0; i < text.length; i++) {
    var result = text.charAt(i);

    if (result == "e" || result == "o" || result == "a" || result == "u") {
        collect += "i";
    } else {
        collect += result;
    }
}

console.log(collect);

To avoid returning the letter for each iteration, accumulate the results in a single variable. Once the loop has completed, return the final value stored in the variable.
