 * @param {Function} - the function to obtain the sort key for each element

 * @example
 *
 * 'use strict'
 * const sortBy = require('@eluvio/elv-js-helpers/Functional/sortBy')
 *
 * const sortByName = sortBy(x => x.name)
 * const sortByNameCaseInsensitive = sortBy(x => x.name.toLowerCase())
 *
 * sortByName([
 *   {name: "alpha"},
 *   {name: "Bravo"},
 *   {name: "charlie"}
 * ]).map(x => x.name)                //=> ['Bravo', 'alpha', 'charlie']
 *
 * sortByNameCaseInsensitive([
 *   {name: "alpha"},
 *   {name: "Bravo"},
 *   {name: "charlie"}
