/**
 * @name startOfTomorrow
 * @category Day Helpers
 * @summary Return the start of tomorrow.
 * @pure false
 *
 * @description
 * Return the start of tomorrow.
 *
 * > ⚠️ Please note that this function is not present in the FP submodule as
 * > it uses `new Date()` internally hence impure and can't be safely curried.
 *
 * ### v2.0.0 breaking changes:
 *
 * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
 *
 * @returns {Date} the start of tomorrow
 *
 * @example
 * // If today is 6 October 2014:
 * const result = startOfTomorrow()
 * //=> Tue Oct 7 2014 00:00:00
