4. queues you want to start running any time you add new items
5. any simple or complex queue operations
6. base class to extend
7. anything else that needs a queue
8. Anything which needs a stack instead of a queue.
# Stable and easy to use
Works great in node.js, webpack, browserify, or any other commonjs loader or compiler. To use in plain old vanilla browser javascript without common js just replace the requires in the examples with script tags. We show that below too.
` js-queue ` also exposes the ` easy-stack ` stack via ` require('js-queue/stack.js') ` this file exposes an ES6 stack which allows for Last In First Out (LIFO) queuing. This can come in handy depending on your application needs, check out the [easy-stack javascript documentation](https://github.com/RIAEvangelist/easy-stack) it follows the ` js-queue ` interface but is node 6 or greater as it uses ES6 classes.
**npm install js-queue**

|add|function|any number of functions| |adds all parameter functions to queue and starts execution if autoRun is true, queue is not already running and queue is not forcibly stopped |
|next|function| | |executes next item in queue if queue is not forcibly stopped|
|clear|function| | |removes remaining items in the queue|
|contents|Array| | | Queue instance contents |
|autoRun|Bool| | true |should autoRun queue when new item added|
|stop|Bool| | false |setting this to true will forcibly prevent the queue from executing|
### Basic queue use in node, react, browserify, webpack or any other commonjs implementation
```javascript
var Queue=require('js-queue');
//create a new queue instance
var queue=new Queue;
for(var i=0; i<50;i++){
//add a bunch of stuff to the queue
queue.add(makeRequest);
}
function makeRequest(){
//do stuff
console.log('making some request');
this.next();
}
```
### Basic browser use
The only difference is including via a script tag instead of using require.
```html
<html>
<head>
<!-- this is the only difference -->
<scriptsrc='./queue-vanilla.js'></script>
<script>
console.log('my awesome app script');
var queue=new Queue;
for(var i=0; i<50;i++){
queue.add(makeRequest);
}
function makeRequest(){
console.log('making some request');
this.next();
}
</script>
</head>
<body>
</body>
</html>
```
### Basic use with websockets in node, react, browserify, webpack or any other commonjs implementation
This allows you to start adding requests immediately and only execute if the websocket is connected. To use in plain browser based JS without webpack or browserify just replace the requires with the script tag.
```javascript
var Queue=require('js-queue');
//ws-share just makes it easier to share websocket code and ensure you don't open a websocket more than once
var WS=require('ws-share');
//js-message makes it easy to create and parse normalized JSON messages.
