Time Handling Data Structure in Java script

## Expirable List

Entries moves to list of expired elements after a certain time. And deleted after defined conditions are met. You can use this datatype in multiple ways, Eg

- deleting sessions after a predefined inactive time.

- cache management

- token expiry

```js

const ExpirableList = require("tsds/ExpirableList");

const onExpiry = (key, data) => { ... };

const onCleanup = () => { ... };

const list = new ExpirableList({

  entryLifespan: 1000, 

  cleanupInterval: 2500,

  maxExpiredEntries: 1000

  },onExpiry, onCleanup);

list.add(12345);

list.add("abc", { data: "something"});

list.add("custom life", { data: "something"}, 1500);

const data = list.get("abc");

:

list.delayExpiry("abc"), 600);

:

list.pause(); // pause the list to expire any existing entity

list.resume();

:

list.life(12345); // how long a key is in this list

list.removeEntry(12345);

:

list.forEachExpired((k,v)=>{

  :

});

list.forEachNonExpired((k,v)=>{

  :

});

:

list.clean(); //to manually clean the list of expired entities

```
