| 如何进行一个深拷贝,是数组且去重。 | |
| 如:[1,2,3],[2,3,4,5] -> [1,4,5] | |
| [1,2,3], {a:6, b:3} -> [1,2,3, a:6, b:3] | |
| 就是如何简单实现类jquery的$.extend(true, a, b)的效果。 | |
| 但与 | |
| jQuery.extend(true,[1,2,3],[2,3]) // [2,3,3] | |
| 区别是题目要求得到是: 2,3,取其中不重复的。 | |
| PS: | |
| 1. 回复时注意加上下面这句话,才会有语法高亮或格式缩进。 | |
| ```javascript | |
| // you code | |
| ``` | |
| 2. 粘贴代码时请使用shift+tab,缩进前面的空白。 |
