lodash省略的替代方法

// 排除特定属性
function omit(obj, keysToOmit) {
  return Object.keys(obj).reduce((result, key) => {
    if (!keysToOmit.includes(key)) {
      result[key] = obj[key];
    }
    return result;
  }, {});
}

// 选择特定属性
function pick(obj, keysToPick) {
  return Object.keys(obj).reduce((result, key) => {
    if (keysToPick.includes(key)) {
      result[key] = obj[key];
    }
    return result;
  }, {});
}

// 示例
const obj = { a: 1, b: 2, c: 3 };
const omitted = omit(obj, ['b']); // { a: 1, c: 3 }
const picked = pick(obj, ['a', 'c']); // { a: 1, c: 3 }

// 排除特定属性
function omit(obj, keysToOmit) {
  return Object.entries(obj)
    .filter(([key]) => !keysToOmit.includes(key))
    .reduce((result, [key, value]) => {
      result[key] = value;
      return result;
    }, {});
}

// 选择特定属性
function pick(obj, keysToPick) {
  return Object.entries(obj)
    .filter(([key]) => keysToPick.includes(key))
    .reduce((result, [key, value]) => {
      result[key] = value;
      return result;
    }, {});
}

// 示例
const obj = { a: 1, b: 2, c: 3 };
const omitted = omit(obj, ['b']); // { a: 1, c: 3 }
const picked = pick(obj, ['a', 'c']); // { a: 1, c: 3 }
