A set of JS functions that help in implementing paging.

	import range from 'lodash/range';

	/**
	* Returns the items in a given page.
	* @template T
	* @param {number} offset The index offset based on the given `pageIndex`
	* (precomputed from `calcOffset`).
	* @param {number} itemsPerPage The number of items per page.
	* @param {T[]} items The array of items.

An example of how to use the paging utilities

	import {
	calcPageNumbers,
	calcOffset,
	calcPageCount,
	getPageItems,
	} from './paging-utils';

	// We'll use lodash's `clamp` function
	import clamp from 'lodash/clamp';

A slightly more practical example of how to use the paging utilities

	import {
	calcPageNumbers,
	calcOffset,
	calcPageCount,
	getPageItems,
	} from './paging-utils';

	// We'll use lodash's `clamp` function
	import clamp from 'lodash/clamp';
