Javascript:如何从几个数组和变量构造一个对象？

function constructObject(arr1, arr2, var1, var2) {
  const obj = {};
  
  for (let i = 0; i < arr1.length; i++) {
    const key = arr1[i];
    const value = arr2[i];
    
    obj[key] = value;
  }
  
  obj[var1] = var2;
  
  return obj;
}

// 示例调用
const array1 = ['name', 'age'];
const array2 = ['John', 25];
const variable1 = 'gender';
const variable2 = 'male';

const result = constructObject(array1, array2, variable1, variable2);
console.log(result);

{
  name: 'John',
  age: 25,
  gender: 'male'
}
