is-odd

A simple Node.js utility to check whether a number is odd.

Installation

Install the package via npm:

npm install is-odd

Usage

Import the package and use the isOdd function to check if a number is odd:

const isOdd = require('is-odd');

console.log(isOdd(3)); // true
console.log(isOdd(4)); // false
console.log(isOdd(0)); // false
console.log(isOdd(-5)); // true

How It Works

The isOdd function determines whether a number is odd by checking if it is not divisible by 2:

function isOdd(n) {
    return n % 2 !== 0;
}

• Odd Numbers: Return true.
• Even Numbers: Return false.
• Zero: Return false.
• Negative Numbers: Return true for odd negatives, false for even negatives.

Examples

| Input | Output | |--------|--------| | 3 | true | | 4 | false| | 0 | false| | -5 | true | | -6 | false|

Key Features

• Lightweight: No dependencies.
• Cross-Environment: Works in Node.js and browser environments.
• Simple Logic: Handles both positive and negative numbers seamlessly.
