TypeScript Bidirectional Map

A TypeScript Version of @educastellano's BiDirectional Map

Create "key/value" collections of one-to-one correspondence. Internally it uses two Map objects, so both keys and values can be of any type.

Install

npm install ts-bidirectional-map --save

Usage

``ts
import BiMap from 'ts-bidirectional-map';

// Create an empty map
const map = new BiMap();
map.set('bob', 'alice');
map.get('bob'); // 'alice'
map.getKey('alice'); // 'bob'

map2.has('bob'); // true
map2.hasValue('alice'); // true
map2.deleteValue('alice');
``
