js中的深拷贝手写

在JavaScript中，可以通过手写代码来实现深拷贝。以下是一种常见的手写深拷贝方法: ```javascript function deepClone(obj) { if (typeof obj !== 'object' || obj === null) { return obj; } let newObj = Array.isArray(obj) ? [] : {}; for (let key in obj) { if (obj.hasOwnProperty(key)) { newObj[key = deepClone(obj[key]); } } return newObj; } ``` 这个方法可以处理对象中包含函数、undefined和Symbol等类型的值，不会丢失它们。它会递归地复制对象的所有属性和嵌套对象，确保生成的副本是独立于原始对象的。你可以将要拷贝的对象作为参数传递给deepClone函数，函数会返回一个新的深拷贝对象。123 #### 引用[.reference_title] - *1* *2* [手写JS—深拷贝](https://blog.csdn.net/qq_33839972/article/details/128241122)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 50%"] - *3* [js手写深拷贝](https://blog.csdn.net/h220801__zzl/article/details/129319480)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 50%"] [ .reference_list ]
