オブジェクトのプロパティ名でループする

More than 1 year has passed since last update.

Object.keys().forEach ... とかって、毎回書くのちょっとだけ面倒ではないのだろうかと思いました。

const objectKeyValueForEach = (obj, func) => {
  Object.keys(obj).forEach((key, index, array) => {
    func(key, obj[key], index, array);
  });
}

var object1 = {
  value1: 'abc',
  value2: 123,
  obj3: {
    value: 'val1'
  }
};

objectKeyValueForEach(object1, (key, value) => {
  console.log(key + ' ' + value);
});
//実行結果
  value1 abc
  value2 123
  obj3 [object Object]
