int to string without need

Feb 16.2021

i am new to JavaScript and i have no idea why the function is not seeing the integer as a number, its suing it as a string and when i load it, it says undefined; help.

[code]const calcAverage = () => {
//ITS A NUMBER HERE
const DolphinScore = (44 + 23 + 71) / 3
const KoalaScore = (65 + 54 + 49) / 3

return

}

calcAverage()

function checkWinner(DolphinScore, KoalaScore) {

const koalaAvg = KoalaScore
const dolphinAvg = DolphinScore

if (dolphinAvg => koalaAvg * 2) { //ITS NOT A NUMBER
console.log(`dolphins win (${dolphinAvg} to ${koalaAvg})`)
} //WHY IS IT A STRING
else if (koalaAvg => dolphinAvg * 2) {
console.log(`koalas win (${dolphinAvg} to ${koalaAvg})`)
}

else {
console.log(`no one wins (${dolphinAvg} to ${koalaAvg})`)
}
return
}

checkWinner()[/code]

Unfortunately single backtics don't work reliably when posting code. You better use code tags: `your code here` or triple backtics.

I edited your posting accordingly.

  • 1. DolphinScore and KoalaScore are defined locally in your function calcAverage. They are not available outside this function.

  • 2. You have defined two parameters for the function checkWinner but you don't hand them over when calling it. Therefore these parameters are undefined. My output of console.log reads:

    • >dolphins win (undefined to undefined)

    @SempervivumFeb 17.2021 — The way you coded the calls of your functions it's not possible to hand over them as they are not available outside of the function calcAverage. I recommend this code:
    const calcAverage = () => {
    //ITS A NUMBER HERE
    const DolphinScore = (44 + 23 + 71) / 3
    const KoalaScore = (65 + 54 + 49) / 3
    // return object containing both scores for dolphin and koala
    return {dolphin: DolphinScore, koala: KoalaScore};
    }

    function checkWinner() {
    // Get averages
    const averages = calcAverage();
    // Extract average for each animal from object
    const koalaAvg = averages.koala;
    const dolphinAvg = averages.dolphin;

    if (dolphinAvg => koalaAvg * 2) { //ITS NOT A NUMBER
    console.log(<span><code>dolphins win (${dolphinAvg} to ${koalaAvg})</code></span>)
    } //WHY IS IT A STRING
    else if (koalaAvg =&gt; dolphinAvg * 2) {
    console.log(<span><code>koalas win (${dolphinAvg} to ${koalaAvg})</code></span>)
    }

    else {
    console.log(<span><code>no one wins (${dolphinAvg} to ${koalaAvg})</code></span>)
    }
    return
    }

    checkWinner()
