CheeseNaN

CheeseNaN is a lightweight and versatile utility library for robust number validation in JavaScript and TypeScript. It simplifies working with numbers by providing a suite of functions to handle edge cases, perform checks, and validate mathematical properties.

---

Features

• 🧀 Robust NaN checks: Beyond isNaN and Number.isNaN.
• 🧮 Comprehensive number tests: Positive, negative, zero, even, odd, integers, floats.
• 📐 Mathematical utilities: Prime numbers, powers of n, perfect squares.
• 🎛 Custom checks: Validate ranges, divisibility, and more.

---

Installation

Install via npm or yarn:

npm install cheesenan

Or use a CDN for vanilla projects:

import * as cheesenan from 'https://unpkg.com/statello@latest/dist/cheesenan.min.js'

---

Usage

Basic Checks

import { cheeseNaN, cheeseValidNumber, cheeseInteger } from 'cheesenan';

console.log(cheeseNaN(NaN)); // true
console.log(cheeseValidNumber(42)); // true
console.log(cheeseInteger(42.5)); // false

Advanced Checks

import { cheesePrime, cheeseWithinRange, cheesePowerOfN } from 'cheesenan';

console.log(cheesePrime(7)); // true
console.log(cheeseWithinRange(10, 5, 15)); // true
console.log(cheesePowerOfN(16, 2)); // true (16 is 2^4)
console.log(cheesePowerOfN(27, 3)); // true (27 is 3^3)

Working with Arrays

import { cheeseAllAreNumbers, cheeseSomeAreNaN } from 'cheesenan';

console.log(cheeseAllAreNumbers([1, 2, 3])); // true
console.log(cheeseSomeAreNaN([1, NaN, 3])); // true

API Reference

Number Validation

• cheeseNaN(value: any): boolean
  Returns true if the value is NaN or not a number.

• cheeseValidNumber(value: any): boolean
  Returns true if the value is a finite number.

• cheeseInteger(value: any): boolean
  Returns true if the value is an integer.

• cheeseFloat(value: any): boolean
  Returns true if the value is a finite float (non-integer).

• cheeseNonZeroNumber(value: any): boolean
  Returns true if the value is a non-zero number.

---

Mathematical Properties

• cheesePositive(value: any): boolean
  Returns true if the value is a positive number.

• cheeseNegative(value: any): boolean
  Returns true if the value is a negative number.

• cheesePrime(value: any): boolean
  Returns true if the value is a prime number.

• cheesePowerOfN(value: any, n: number): boolean
  Returns true if the value is a power of n.

• cheesePerfectSquare(value: any): boolean
  Returns true if the value is a perfect square.

---

Range and Divisibility

• cheeseWithinRange(value: any, min: number, max: number): boolean
  Returns true if the value is within the range [min, max].

• cheeseDivisibleBy(value: any, divisor: number): boolean
  Returns true if the value is divisible by the given divisor.

---

Working with Arrays

• cheeseAllAreNumbers(values: any[]): boolean
  Returns true if all elements in the array are valid numbers.

• cheeseSomeAreNaN(values: any[]): boolean
  Returns true if at least one element in the array is NaN.

---

Roadmap

1. Performance Optimization: Improve speed for large datasets (e.g., prime number checks).
2. Extended Mathematical Utilities: Add functions for Fibonacci checks, GCD/LCM, etc.
3. Type-safe Input Validation: Enhance TypeScript support with stricter typings.
4. Integration: Provide plugins for frameworks like React or Vue for runtime validation.
