Small Orange Collection Handler

Lightweight collection handler based on lodash.

API

	constructor(source: Array<string | object>, indexAttr?: string);
	before(item: string | number): instance;
	after(item: string | number): instance;
	limit(n: number): instance;
	desc(): instance;
	stats: {
		count: number,
		total: number,
		before: string | number,
		after: string | number
	};
	items: Array<string | object>;

Sample

	const CollectionHandler = require('smallorange-collection-handler');

	const array = new CollectionHandler(['a', 'b', 'c', 'd', 'e', 'f']);
	const collection = new CollectionHandler([{
		id: 1,
		value: 'a'
	}, {
		id: 2,
		value: 'b'
	}, {
		id: 3,
		value: 'c'
	}, {
		id: 4,
		value: 'd'
	}, {
		id: 5,
		value: 'e'
	}, {
		id: 6,
		value: 'f'
	}], 'id');

	const arrayResult = array
		.before('d')
		.limit(2);

	const collectionResult = array
		.before(4)
		.limit(2);

	console.log(arrayResult.items); // ['b', 'c']
	console.log(arrayResult.stats); // {count: 2, before: 'b', after: 'c', total: 6}
	console.log(arrayResult.items); // [{id: 2, value: 'b'}, {id: 3, value: 'c'}]
	console.log(arrayResult.stats); // {count: 2, before: 'b', after: 'c', total: 6}
