es-toolkit/dist/compat/function/after.js

A state-of-the-art, high-performance JavaScript utility library with a small bundle size and strong type annotations.

const require_toInteger = require("../util/toInteger.js");
//#region src/compat/function/after.ts
/**
* 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 n - The number of calls before `func` is invoked.
* @param func - The function to restrict.
* @returns 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!');
* });
*
* saves.forEach(type => {
*   asyncSave({ 'type': type, 'complete': done });
* });
* // => Logs 'done saving!' after the two async saves have completed.
