+##Explanation

+In Python, the logic expressed as return number % 2 == 0, which evaluates to true or false.
+In JavaScript, the same idea is written as return number % 2 ===0, which evaluates to true or false.
+The main difference lies in the syntax Python uses def to define functions and print() to display results, 
+while JavaScript uses the function keyword and console.log() to output results. When tested with the numbers 
+6 and 9, both versions correctly identify 6 as even and 9 as odd, demonstrating that although the syntax differs
+between the 2 languages, the underlying logic is exactly the same.
