* The opposite of `before`. This 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. | |
