Check for a value in an array of objects

Question

function weatherCodes(){
let codes = [{sunny:[1001]},{cloudy:[1002,1003]}]
let theCode = 1003
};

How do I check my array of objects to find if one of them contains my variable theCode

Answer 1

Using flat() and includes() Simple reference provided for you

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());

Another option

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());
