/***Is It Even?*** 
In this Kata we are passing a number (n) into a function.

Your code will determine if the number passed is even (or not).

The function needs to return either a true or false.

Numbers may be positive or negative, integers or floats.

Floats with decimal part non equal to zero are considered UNeven for this kata.*/

const testEven = (n) =>{
    if (n%2 === 0){
      return true;
    }else {
      return false;
    }
  }

  //refactored
  const testEven = (n) => n%2 === 0;
