Hello guys, I’ve read all the threads but haven’t found a final decision on task 7.

Can anyone explain how I can use the function getAbsoluteDistance() and how I can implement that function on the `compareGuesses()`

function.

I see that we should create something like this function and what goes next?

const humanDifference = getAbsoluteDistance (argument1, argument2)

Please don’t suggest the decision like creating variables

(const humanDifference = Math.abs(targetGuess - humanGuess);

const computerDifference = Math.abs(targetGuess - computerGuess)) because I already did it myself.

Thanks in advance.

If you already have written this function, `getAbsoluteDistance`

that takes two parameters and returns the absolute distance then the only thing that is left to do is to use this function in the `compareGuesses`

function.

In the `compareGuesses`

function you probably have something similar to this:

```
const humanDifference = Math.abs(targetGuess - humanGuess);
const computerDifference = Math.abs(targetGuess - computerGuess);
```

so just change this code to get the absolute distance from `getAbsoluteDistance`

function, isntead of calculating it (`Math.abs(targetGuess - humanGuess)`

).

Thanks for the explanation.

Everything seems to be working now.

I’m going to insert my code here for two reasons: 1) people including you can leave feedback; 2) I think it can be helpful for the future cohorts who have the same questions.

```
let humanScore = 0;
let computerScore = 0;
let currentRoundNumber = 1;
// Write your code below:
const generateTarget = () => {
return Math.floor(Math.random() * 10)
}
console.log(generateTarget());
const compareGuesses = (userGuess, computerGuess, secretTarget) => {
const humanDifference = getAbsoluteDistance(userGuess, secretTarget);
const computerDifference = getAbsoluteDistance(computerGuess, secretTarget);
alertMessage(userGuess);
return computerDifference >= humanDifference;
}
const updateScore = winner => {
if (winner === 'human') {
humanScore++;
}
if (winner === 'computer') {
computerScore++;
}
}
const advanceRound = () => {
currentRoundNumber++;
}
const getAbsoluteDistance = (a1, a2) => {
return (Math.abs((a1 - a2)));
}
const alertMessage = (userGuess) => {
if (userGuess > 9 || userGuess < 0) {
alert('Guess must be between 0 and 9!');
}
};
```

```
let humanScore = 0;
let computerScore = 0;
let currentRoundNumber = 1;
// Called at the start of each new round in order to generate the new secret target number.
const generateTarget = () => {
return Math.floor(Math.random() * 10);
};
// This function will be called at the start of each new round in order to generate the new secret target number.
console.log(generateTarget());
const compareGuesses = (userGuess, computerGuess, targetGuess) => {
/*// Determines which player (human or computer) wins based on which guess is closest to the target.
If both players are tied, the human user should win.
// Return true if the human player wins, and false if the computer player wins.
*/
const userDifference = getAbsoluteDistance(userGuess, targetGuess);
const computerDifference = getAbsoluteDistance(computerGuess, targetGuess);
alertMessage(userGuess);
return computerDifference >= userDifference;
};
// if (userDifference > computerDifference) {
// return false;
// }else if(userDifference < computerDifference){
// return true;
// }else {
// return true;
// }
// This function will be used to correctly increase the winner’s score after each round.
const updateScore = winner =>{
if (winner === 'human'){
humanScore++;
}else if(winner === 'computer'){
computerScore++;
}
}
// This function will be used to update the round number after each round.
const advanceRound () => {
currentRoundNumber++;
};
const getAbsoluteDistance = (x, y) =>{
return (Math.abs((x - y)));
};
// // functionality to check whether the user guess is between 0 and 9 and alert() the user that their number is out of range.
const alertMessage = (userGuess) => {
if (userGuess > 9 || userGuess < 0){
alert('Not in range!');
}
};
```

I have the following code, but my alert message does not display can somebody explain to me why that is? Also, is my getAbsoluteDistance function correct?
