# nocake
nocake is a JavaScript collections library including **Stack**, **Queue**, **PriorityQueue**, **PromiseQueue** and **LinkedList** data structures.
## Examples
```js
import { Stack, Queue, PriorityQueue, PromiseQueue,
LinkedList, DoublyLinkedList, CircularLinkedList } from 'nocake';
let s = new Stack();
s.push(1);
s.push(2);
s.pop(); //=> 2
let q = new Queue();
q.enqueue(1);
q.enqueue(2);
q.dequeue(); //=> 1
let pq = PriorityQueue.of((a, b) => {
if (a.priority < b.priority) {
return 1
}
if (a.priority > b.priority) {
return -1
}
return 0
});
// enqueue(element[, priority])
pq.enqueue(1);
pq.enqueue(3);
pq.enqueue(2);
pq.dequeue(); //=> {element: 3, priority: 3}
pq.dequeue(); //=> {element: 2, priority: 2}
const promisequeue = PromiseQueue.of({ concurrency: 1 });
const asyncTask = (time) => () => { return new Promise(resolve => {
setTimeout(resolve, time)
})};
promisequeue.add(asyncTask(1000), { priority: 1 }).then(() => {
console.log('async task 1000 Done');
});
promisequeue.addAll([asyncTask(2000), asyncTask(4000)], { priority: 2 }).then(() => {
console.log('async task 2000/4000 Done');
});
promisequeue.add(asyncTask(3000), { priority: 3 }).then(() => {
console.log('async task 3000 Done');
});
// async task 1000 Done
// async task 3000 Done
// async task 2000/4000 Done
```
## Installation
```
npm install --save nocake
```
## Usage
You can import one or multiple collections from `nocake`:
```js
import { Stack, Queue, PriorityQueue, PromiseQueue,
LinkedList, DoublyLinkedList, CircularLinkedList } from 'nocake';
// or
const { Stack, Queue, PriorityQueue, PromiseQueue,
LinkedList, DoublyLinkedList, CircularLinkedList } = require('nocake');
```
