A question about JavaScript

Question

I have a question about this code. I don’t know what “ count++ % 2 ==0 “ mean. Especially “count++”. Is this like “0 % 2” and the next one is “1 %2”?
It doesn’t seem it’s looping and adding one to count variable.

var count = 0;
function clickMe(e) {
if (count++ % 2 == 0) {
e.textContent = “o”;
} else {
e.textContent = “x”;
}
}

Answer 1

Thnx Louis

Answer 2

count++ is an increment of 1
so one is added on to count

% is the modulus operator
This finds a remainder after a
division

Such as:

5 % 2 = 1
This is becuase 5/2 only lets 2
go up to 4
Therfore, 5%2 is 5-4 which is 1

== Is the equality operator
