e is a math constant, Euler's number (2,72)

What would you name it instead? I came up with the same solution, but used "item" instead of "e." (Also - how would you use "e" as a number in math? - You got me all curious now!)

interesting solution, you reduce the logic of validate the odd, and only use 1 array.

2 loops

use === instead of ==

O (n^2)

is better to use the === instead of ==, for prevent the coersion

In Math "e" is a number, not sure if is a good idea to name it with "e", but your solution is great!

I think this is not a good idea, because, you need check the input twice, but It is elegant

Your writing is really concise, but I find it executes two extra operations. Under the hood, it converts to boolean, the main intent, then operates "!" twice.
Plus it is harder to read, as the double negation isn't the main propose of the code, but the undelrying conversion that takes place.

if you're just evaluating if something is truthy or falsey, this is a much more concise method:

const validateProperty = (objectForValidate, specificProperty) => !!objectForValidate[specificProperty]

nice!!!

ohhhhhhh!!!!!!
