bignumbertreemap-js v0.5.4

BigNumberTreeMap.js

This is based on treemap-js. This package extended it to support BigNumber in JavaScript; The following is copied from it.

A binary tree based map (aka dictionary) data type for Javascript, keeping keys sorted at all times. Provides O(log n) average case performance for inserting, retrieving and removing values.

Installation

Works with Node.js(treemap.js support Browser, but this package not yet).

Node

Install via npm install bignumbertreemap-js. Then access the TreeMap like this:

const TreeMap = require("bignumbertreemap-js");

Browser

Not support yet(0.5.3);

Usage

const BigNumber = require('bignumber.js');
var map = new TreeMap();

map.set(BigNumber(11.13));

map.set("my first key", "hello");    // keys can be strings, numbers or booleans. Values can be any data type
map.set("second key", [ 1, 3, 4 ]);
map.get("my first key");    // returns "hello"

map.set("my first key", 2342);
map.get("my first key");    // returns 2342

map.getLength();    //  returns 2

map.getMinKey();    // returns "my first key"
map.getMaxKey();    // returns "second key"

map.each(function (value, key) {
    // do something...
});

map.remove("my first key");
map.getLength();    // returns 1

map.getTree();    // returns the backing tree object
