我試圖讓這個函式用兩個不同的輸入運行兩次，但它只運行一次。
編碼：
const data1dolphins = 44 23 71;
const data1Koalas = 65 54 49;
const data2dolphins = 85 54 41;
const data2Koalas = 23 34 27;
function calcAverage(data, dataValue) {
const scoreAverage = data * dataValue
return scoreAverage;
}
const data1DolphinsAverage = calcAverage(data1dolphins, 3)
const data1KoalasAverage = calcAverage(data1Koalas, 3)
const data2DolphinsAverage = calcAverage(data2dolphins, 3)
const data2KoalasAverage = calcAverage(data2Koalas, 3)
function checkWinner(avgTeamOne, avgTeamTwo) {
if (avgTeamOne >= (avgTeamTwo * 2)) {
console.log(`team one won with average score of : ${avgTeamOne}, while team two lost with average score of : ${avgTeamTwo}`)
} else if (avgTeamTwo >= (avgTeamOne * 2)) {
console.log(`team two won with average score of : ${avgTeamTwo}, while team one lost with average score of : ${avgTeamOne}`)
}
// console.log('testing round')
}
console.log('before')
checkWinner(data1DolphinsAverage, data1KoalasAverage)
console.log('middle')
checkWinner(data2DolphinsAverage, data2KoalasAverage)
console.log('after')輸出：
前
一隊以平均分 540 分獲勝，二隊以平均分 252 分負
中間
后

你試過 else 陳述句嗎？
function checkWinner (avgTeamOne,avgTeamTwo){
if(avgTeamOne >= (avgTeamTwo*2)) {
console.log(`team one won with average score of : ${avgTeamOne}, while team two lost with average score of : ${avgTeamTwo}`);
} else if (avgTeamTwo >= (avgTeamOne*2)){
console.log(`team two won with average score of : ${avgTeamTwo}, while team one lost with average score of : ${avgTeamOne}`);
} else { <<
console.log("neither of these things happened."); <<
} <<
}
我發現很難看出您的目的，因為您沒有提供data1dolphins, data1Koalas, data2dolphins, 或 的值data2Koalas，但我猜這是您需要的修復程式。

添加 else 陳述句后該函式運行良好：
const data1dolphins = 44 23 71;
const data1Koalas = 65 54 49;
const data2dolphins = 85 54 41;
const data2Koalas = 23 34 27;
function calcAverage (data,dataValue){
const scoreAverage = data * dataValue
return scoreAverage;
}
const data1DolphinsAverage = calcAverage(data1dolphins,3)
const data1KoalasAverage = calcAverage(data1Koalas,3)
const data2DolphinsAverage = calcAverage(data2dolphins,3)
const data2KoalasAverage = calcAverage(data2Koalas,3)
function checkWinner (avgTeamOne,avgTeamTwo){
if(avgTeamOne >= (2*avgTeamTwo)) {
console.log(`team one won with average score of : ${avgTeamOne}, while team two lost with average score of : ${avgTeamTwo}`)
} else if (avgTeamTwo >= (2*avgTeamOne)){
console.log(`team two won with average score of : ${avgTeamTwo}, while team one lost with average score of : ${avgTeamOne}`)
}else {
console.log('none of the above')
}
}
console.log('before')
checkWinner(data1DolphinsAverage, data1KoalasAverage)
console.log('middle')
checkWinner(data2DolphinsAverage, data2KoalasAverage)
console.log('after')
