Am I Even Or Odd

Is your number even or odd tho?

Yes, n % 2 === 0 does the same thing.

Installation

npm install am-i-even-or-odd

Usage

CommonJS:

const { isItEvenTho, isItOddTho } = require('am-i-even-or-odd');

console.log(isItEvenTho(4)); // true
console.log(isItOddTho(5));  // true

ESM / TypeScript:

import { isItEvenTho, isItOddTho } from 'am-i-even-or-odd';

console.log(isItEvenTho(4)); // true
console.log(isItOddTho(5));  // true

Error handling

Only integers are accepted. Floats, strings, null, undefined, booleans, NaN, and numbers outside JavaScript's safe integer range all throw a TypeError with a message explaining why, rather than silently returning a possibly-wrong answer:

isItEvenTho(4.5);
// TypeError: expected an integer, got number (4.5). Non-integer
// values aren't supported to avoid ambiguity around what counts
// as 'even' or 'odd'.

Command line

Installing the package also gives you a CLI:

$ npx am-i-even-or-odd 42
even

$ npx am-i-even-or-odd 7 --fun
7 is is even! Kidding it's obviously ODD.

--fun swaps the plain even/odd output for a random one-liner with a bit more personality. Invalid input prints a usage error and exits with a non-zero status code, so it plays nice in scripts.
