What happening with this parameter?

JavaScript

Tell us what’s happening:

So I think I know how to solve this activity but I don’t understand what is happening with the parameters being passed into the function:

findElement([1, 2, 3, 4], num => num % 2 === 0);

I don’t understand what is happening here: num % 2 === 0

I realize that we are getting the remainder of a number divided by 2, but what’s going on with the === 0?

Sometimes you just need to tinker and make a loop that prints stuff :smiley:
