A comprehensive utility library for JavaScript and TypeScript that provides a wide range of functions for common programming tasks, including mathematical operations, date manipulations, array and object handling, string utilities, and more.

import type { AnyFunction } from "..";
/**
 * Creates a function that invokes the original function only before it's called n times.
 * @param {number} times - The number of calls before the original function stops being invoked.
 * @param {Function} fn - The function to restrict.
 * @returns {Function} The new restricted function.
 * @example
 * let count = 0;
 * const incrementBeforeThree = before(() => ++count, 3);
 * incrementBeforeThree(); // 1
 * incrementBeforeThree(); // 2
 * incrementBeforeThree(); // 2 (doesn't increment anymore)
