Usage

// CommonJS
const collections = require('@augu/collections');

// ES6+
import collections from '@augu/collections';

// Collection: Key-value pair that is an extension of [Map]
const coll = new collections.Collection(); // Create a empty one
const coll = new collections.Collection({
  // Create one with key-value pairs
  key: 'value',
  [Symbol('key')]: 'value',
});

coll.get('key'); // the value if added or undefined
coll.set('key', 'value'); // the value if the key isn't added

coll.filter((value) => value === 'value'); // Returns a Array of values if the predicate is true
coll.map((v) => v); // Returns a Array of values that are mapped by it's predicate function
coll.reduce((curr, acc) => curr + acc, 0); // Implementation of Array.reduce
coll.sort((a, b) => a - b); // Implementation of Array.sort

// Queue: Queue-based system with a timer extension to do time-based queues
const queue = new collections.Queue(); // Create a empty Queue
const queue = new collections.Queue(['a', 'b', 'c']); // Create one with values being added

queue.get(0); // Get a item from it's index
queue.add('c'); // Add a item to the queue
queue.delete(2); // Delete a item from it's index
queue.filter((c) => c === 'a'); // Filter out the queue from a predicate function
queue.map((u) => u); // Map out anything from a predicate function
