Challenge Project: Number Guesser (codeacademy)

script.js

let humanScore = 0;
let computerScore = 0;
let currentRoundNumber = 1;

// Write your code below:
function generateTarget() {
    return Math.floor(Math.random() * 9);
};

function compareGuesses(human,comp,secret) {
    let humanGuess = Math.abs(human - secret);
    let compGuess = Math.abs(comp - secret);
    // make more compact? like:
    return (humanGuess <= compGuess) ? true : false;
};

function updateScore(winner) {
    switch (winner) {
        case ('human'):
            humanScore += 1;
            break;
        case ('computer'):
            computerScore += 1;
            break;
        default: 
            'error'
            break;
    }
};

function advanceRound() {
    currentRoundNumber += 1;
};

Hey Pomomi! Great job on finishing the project. I am here because you said if there is any way we can refactor your code and there is! For your functions generateTarget() and advanceRound() you can make them one liners! How?
Below will be an example for your generateTarget() function. The same principle can be applied to your advanceRound() function and also you can use the increment operator to add 1 to currentRoundNumber to make it look nicer!
const generateTarget = () => Math.floor(Math.random() * 9);
Now you are wondering what the heck did I do! Well, let me break it down.

I changed your function into an arrow function (ES6 syntax) which is typically written as:
const functionName = (parameter) => {
Some code here
Maybe some more code here
}
BUT if you recall the lesson they stated if you are returning ONE LINE you can skip the figure brackets (or curly braces which are these -> {} ) and just write what you want to return. Like this:
const functionName = (parameter) => codeWeWantToReturnHere
In this instance, we want to return Math.floor(Math.random() * 9) so we can just write it the way I did. If you want to learn more about this, go back to Learn JavaScript Syntax: Functions Calling a function. You will see a lesson called Concise Body Arrow Functions on page 10!

@Allen-Valdez A single line would definitely look a lot nicer! Thank you so much for taking the time to write such a wonderfully detailed comment. I really appreciate the help!

@pomomi Yeah no problem! If you have any questions please feel free to reach out!
