Circular Linked List

This is a circular singly linked list implementation that follows the itterator interface, being a drop in replacement for iterable structure when you need a list. Technically this behaves like a stack.

Usage Deno

import List from "https://deno.land/x/list/mod.ts";

Usage Node

npm install --save @denox/list

import List from "@denox/list";

API

Initialization

The only argument is entries and it is optional, allowing prepopulating the list.

const list = new List(); // Creates an empty list
const listWithData = new List(["value1", "value2"]); // Creates a list with 2 entries

Push

Add a value to begining of the list.

list.push("value");

Pop

Retrieve a value from begining of the list.

list.pop(); // "value"

Peek

Retrieve a value from begining of the list, similar with pop but without changing the list.

// Same behavior as get but without moving the key/value to the end of the eviction queue
list.peek("key");

Clear

Clear everything from the list, leaving the list empty.

list.clear();

Size

Get the current size of the list.

list.size; // Number

Keys, Values, Entries

Get the iterators for keys, values or entries reversed order based on the insetion.

Array.from(list.keys()); // [value1, value2, ...]
Array.from(list.values()); // [value1, value2, ...]
Array.from(list.entries()); // [[value1, value1], [value2, value2], ...]

ForEach

Iterate over the values in the reverse insersion order.

list.forEach((value, key, list) => {
    //...
});
