一款参考 C++ STL 实现的 JavaScript 标准数据结构库

English | 简体中文

## ✨ 包含的数据结构 - **Stack** - 先进后出的堆栈 - **Queue** - 先进先出的队列 - **PriorityQueue** - 堆实现的优先级队列 - **Vector** - 受保护的数组，不能直接操作像 `length` 这样的属性 - **LinkList** - 非连续内存地址的链表 - **Deque** - 双端队列，向前和向后插入元素或按索引获取元素的时间复杂度为 O(1) - **OrderedSet** - 由红黑树实现的排序集合 - **OrderedMap** - 由红黑树实现的排序字典 - **HashSet** - 参考 [ES6 Set polyfill](https://github.com/rousan/collections-es6) 实现的哈希集合 - **HashMap** - 参考 [ES6 Set polyfill](https://github.com/rousan/collections-es6) 实现的哈希字典 ## ⚔️ 基准测试我们和其他数据结构库进行了基准测试，在某些场景我们甚至超过了当前最流行的库查看 [benchmark](https://js-sdsl.org/#/zh-cn/test/benchmark-analyze) 以获取更多信息 ## 🖥 支持的平台 | ![][Edge-Icon]
