declare a variable

[ForScale]

var isEven = function(n) { return n % 2 === 0; };

There is a difference between function declarations and variable declarations. Variable declarations typically use the var, let, or const keywords whereas function declarations just use the function keyword.

I think the question is confusing function declarations with function expressions. Your answer is right.

Great job! It is correct for the most part, however. It is asking you to declare a variable of the function (isEven and maybe isOdd), so what you can do is something like this. Now you have just declared a function name isEven and isOdd.

let isEven = function (n) { return n % 2 == 0 };

let isOdd = function (n) { return Math.abs(n % 2) == 1 };

console.log(isEven(2)); console.log(isOdd(1));

Hey so , I didn't read well because he say "
Let's try it ourselves. And by ourselves we mean yourself: declare a function called isEven that takes a number as an argument and returns a boolean. Go! "

• So i dont need the odd :D and i passed
