## Why
|
|
|
|
Do you envy C++ with [STL]() (std::), Python with [collections](), and Java with [java.util]() ? Well, no need to envy
|
|
anymore! JavaScript and TypeScript now have [data-structure-typed]().**`Benchmark`** compared with C++ STL. **`API standards`** aligned with ES6 and Java. **`Usability`** is comparable to Python

### We provide data structures that are not available in JS/TS
|
|
|
|
Heap, Binary Tree, RedBlack Tree, Linked List, Deque, Trie, Directed Graph, Undirected Graph, BST, AVL Tree, Priority Queue, Queue, Tree Multiset, Linked List.
|
|
|
|
|
|
### Performance surpasses that of native JS/TS

## Installation and Usage
|
|
|
|
Now you can use it in Node.js and browser environments
|
|
|
|
CommonJS:**`require export.modules =`**
|
|
|
|
ESModule: **`import export`**
|
|
|
|
Typescript: **`import export`**
|
|
|
|
UMD: **`var Deque = dataStructureTyped.Deque`**
|
|
|
|
|
|
### npm
|
|
|
|
```bash
|
|
npm i data-structure-typed --save
|
|
```
|
|
|
|
### yarn
|
|
|
|
```bash
|
|
yarn add data-structure-typed
|
|
```
|
|
|
|
```js
|
|
import {
|
|
BinaryTree, Graph, Queue, Stack, PriorityQueue, BST, Trie, DoublyLinkedList,
|
|
AVLTree, MinHeap, SinglyLinkedList, DirectedGraph, TreeMultimap,
|
|
