 * The opposite of `before`his method creates a function that invokes

 * @category Function
 * @param {number} n The number of calls before `func` is invoked.
 * @param {Function} func The function to restrict.
 * @returns {Function} Returns the new restricted function.
 * @example
 *
 * const saves = ['profile', 'settings']
 * const done = after(saves.length, () => console.log('done saving!'))
 *
 * forEach(saves, type => asyncSave({ 'type': type, 'complete': done }))
 * // => Logs 'done saving!' after the two async saves have completed.
