Why (i % 3 == 0) why it need to == 0 I didn't get it ?

Well it's hard to know exactly which exercise/challenge/video you're referencing. But what they're asking is this: is the value stored in the variable i evenly divisible by 3.

Let's look at some examples.

4 divided by three results in 1 with a remainder of 1. That means 4 % 3 ==1.

5 divided by 3 results in 1 with a remainder of 2. So 5 % 3 == 2.

6 divided by 3 results in 2 with a remainder of 0. 6 % 3 == 0. Six is evenly divisible by three.

Hope this helps!
