/**
* The opposite of `before`his method creates a function that invokes
* `func` once it's called `n` or more times.
*
* @since 0.1.0
* @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.
