* The opposite of `_.before`; this method creates a function that invokes
|
||
|
|
* `func` once it's called `n` or more times.
|
||
|
|
*
|
||
|
|
* @template TFunc - The type of the function to be invoked.
|
||
|
|
* @param {number} n - The number of calls before `func` is invoked.
|
||
|
|
* @param {TFunc} func - The function to restrict.
|
||
|
|
* @returns {TFunc} Returns the new restricted function.
|
||
|
|
* @throws {TypeError} - If `func` is not a function.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* const saves = ['profile', 'settings'];
|
||
|
|
* const done = after(saves.length, () => {
|
||
|
|
* console.log('done saving!');

* asyncSave({ 'type': type, 'complete': done });

* // => Logs 'done saving!' after the two async saves have completed.
