Javascript通过匹配条件删除项的匹配项

function removeItemsByCondition(arr, condition) {
  for (let i = arr.length - 1; i >= 0; i--) {
    if (condition(arr[i])) {
      arr.splice(i, 1);
    }
  }
  return arr;
}

// 示例用法
const numbers = [1, 2, 3, 4, 5];
const condition = (item) => item % 2 === 0; // 删除偶数项
const result = removeItemsByCondition(numbers, condition);
console.log(result); // 输出 [1, 3, 5]

function removePropertiesByCondition(obj, condition) {
  for (let key in obj) {
    if (condition(obj[key])) {
      delete obj[key];
    }
  }
  return obj;
}

// 示例用法
const person = {
  name: 'John',
  age: 30,
  gender: 'male',
};

const condition = (value) => typeof value === 'string'; // 删除字符串属性
const result = removePropertiesByCondition(person, condition);
console.log(result); // 输出 { age: 30 }
