The is-even npm package is a simple utility that allows you to check if a number is even. It is useful for basic numerical validations and can be easily integrated into larger projects where such checks are necessary.
Check if a number is even
This feature allows you to check if a given number is even. The function returns true if the number is even and false if it is not.
const isEven = require('is-even');
console.log(isEven(4)); // true
console.log(isEven(3)); // falseThe is-odd package provides functionality to check if a number is odd. It is similar to is-even but focuses on odd numbers instead. It can be used in conjunction with is-even for comprehensive numerical checks.
Lodash is a utility library that provides a wide range of functions for common programming tasks, including numerical checks. The _.isEven function in lodash can be used to check if a number is even, similar to the is-even package, but lodash offers much more functionality beyond this.
The number-is-nan package checks if a value is NaN (Not-a-Number). While it does not directly check for even numbers, it is often used in conjunction with numerical validation libraries like is-even to ensure comprehensive number validation.
Return true if the given number is even.
Install with npm:
$ npm install --save is-even
var isEven = require('is-even');
isEven(0);
//=> true
isEven('1');
//=> false
isEven(2);
//=> true
isEven('3');
//=> false
