Write a JavaScript function named reverse, which is used as an input parameter of the “sort" function, l.e., sori (reverse), to implement the following requirements: Input: A line of text, using prompt. Output: The words of the input text, in alphabetical reverse order. Note: you are only required to write the reverse function, rather than the entire html code

Here is the JavaScript function named `reverse` that can be used as an input parameter of the `sort` function:

function reverse(a, b) {
  if (a < b) {
    return 1;
  } else if (a > b) {
    return -1;
  } else {
    return 0;
  }
}

To use this `reverse` function with the `sort` function to output the words of an input text in alphabetical reverse order, you can follow these steps:

1. Use the `prompt` function to get a line of text from the user and store it in a variable:

let inputText = prompt("Enter a line of text:");

2. Split the input text into an array of words using the `split` function:

let words = inputText.split(" ");

3. Sort the words in alphabetical order using the `sort` function and pass the `reverse` function as an input parameter:

words.sort(reverse);

4. Join the sorted words back into a string using the `join` function:

let outputText = words.join(" ");

5. Output the sorted words in alphabetical reverse order to the user:

alert(outputText);

Putting it all together, here's the full code:

function reverse(a, b) {
  if (a < b) {
    return 1;
  } else if (a > b) {
    return -1;
  } else {
    return 0;
  }
}

let inputText = prompt("Enter a line of text:");
let words = inputText.split(" ");
words.sort(reverse);
let outputText = words.join(" ");
alert(outputText);
