Question

functionweatherCodes(){letcodes=[{sunny:[1001]},{cloudy:[1002,1003]}]lettheCode=1003};如何檢查我的物件陣列以找出其中一個是否包含我的變數theCode

使用 flat() 和 includes() 為您提供的簡單參考

function weatherCodes(){
  let codes = [{sunny:[1001]},{cloudy:[1002,1003]}]
  let theCode = 1003
  return codes.some(c => Object.values(c).flat().includes(theCode));
};

console.log(weatherCodes());

另一種選擇

function weatherCodes(){
  let codes = [{sunny:[1001]},{cloudy:[1002,1003]}]
  let theCode = 1003
  let values = codes.flatMap(c => Object.values(c)).flat()
  return values.includes(theCode)
};

console.log(weatherCodes());
