JavaScript Remainders Query

Hi All,

Having trouble understanding this. The way I get it is it is the result of dividing two numbers, multiplying the result by itself and then taking the answer and subtracting it from the initial amount?

I think the example they gave was slightly confusing.

Just think of it as regular division in math, if you divide 5 by 2, what will be left over? 1.

So you would just set var remainder = 11 % 3;
