The ES6 Arrow Hub

Mission Briefing

The Guild's sorcerers have adopted a faster, sleeker way of casting spells. You must upgrade your function syntax to meet the modern standard to determine if a number is even.

The Concept: Arrow Functions

Modern JavaScript introduced a shorter way to write functions called Arrow Functions. They use the => syntax and are the standard for professional development today. Example: const add = (a, b) => a + b; (This is an implicit return!)

The Objective

Your mission is to write an arrow function called checkEven that receives a number num.

1. Use arrow function syntax (() => {}).
2. Use the modulo operator (%) to check if the number is perfectly divisible by 2.
3. Return true if the number is even, and false if it is odd.
