5 // console.log(_.setWith(object, '[0][1]', 'a', Array)); // 返回个寂寞 参数: 1). '[0][1]' 是key,字符串形式的数组,对象是两层嵌套 2). 'a' 是值 3). Object 表示返回的是对象 3、result _.result() 获取对象属性 与get一样都是取对象属性的,只不过它遇到函数的属性时,
在转换函数中,我们将每个元素转换为一个包含id和name属性的对象。最后,我们打印输出了转换后的对象数组objectArray。 这种将数组转换为对象数组的操作在实际开发中非常常见。例如,当从数据库中获取到一组数据时,可能会将其转换为对象数组进行进一步处理或展示。
