## 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

### Data structures available

We provide data structures that are not available in JS/TS
Heap, Binary Tree, Red Black Tree, Linked List, Deque, Trie, Directed Graph, Undirected Graph, BST, AVL Tree, Priority
Queue, Queue, Tree Multiset.

### Performance

Performance surpasses that of native JS/TS

### Conciseness and uniformity
In Java.utils, you need to memorize a table for all sequential data structures(Queue, Deque, LinkedList),

<table>
        <thead>
            <tr>
                <th>Java ArrayList</th>
                <th>Java Queue</th>
                <th>Java ArrayDeque</th>
                <th>Java LinkedList</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>add</td>
                <td>offer</td>
                <td>push</td>
                <td>push</td>
            </tr>
            <tr>
                <td>remove</td>
                <td>poll</td>
                <td>removeLast</td>
                <td>removeLast</td>
            </tr>
            <tr>
                <td>remove</td>
                <td>poll</td>
                <td>removeFirst</td>
                <td>removeFirst</td>
            </tr>
            <tr>
                <td>add(0, element)</td>
                <td>offerFirst</td>
                <td>unshift</td>
                <td>unshift</td>
            </tr>
        </tbody>
    </table>

whereas in our data-structure-typed, you **only** need to remember four methods: `push`, `pop`, `shift`, and `unshift` for all sequential data structures.

## Software Engineering Design Standards

We strictly adhere to computer science theory and software development standards. Our LinkedList is designed in the
traditional sense of the LinkedList data structure, and we refrain from substituting it with a Deque solely for the
purpose of showcasing performance test data. However, we have also implemented a Deque based on a dynamic array
concurrently.

## supported module system

Now you can use it in Node.js and browser environments

CommonJS:**`require export.modules =`**

ESModule:&nbsp;&nbsp;&nbsp;**`import export`**

Typescript:&nbsp;&nbsp;&nbsp;**`import export`**

UMD:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**`var Deque = dataStructureTyped.Deque`**

### CDN

Copy the line below into the head tag in an HTML document.

#### development

```html

<script src='https://cdn.jsdelivr.net/npm/data-structure-typed/dist/umd/data-structure-typed.js'></script>
```

#### production

```html

<script src='https://cdn.jsdelivr.net/npm/data-structure-typed/dist/umd/data-structure-typed.min.js'></script>
```

Copy the code below into the script tag of your HTML, and you're good to go with your development.

```js
const { Heap } = dataStructureTyped;
const {
  BinaryTree, Graph, Queue, Stack, PriorityQueue, BST, Trie, DoublyLinkedList,
  AVLTree, MinHeap, SinglyLinkedList, DirectedGraph, TreeMultiMap,
  DirectedVertex, AVLTreeNode
} = dataStructureTyped;
```
