so you have :

i = i + 1;

instead of writing it like that you juste take off the "i" after the equal sign, and you put the addition sign before the equal sign :

i += 1;

it means that you are adding 1 to the last value of "i".

Lets say you have

var x = 10

Then you do this:

x+= 5

This is saying take x which is 10 , and add 5 to it.

So, x+=5 will give you 15.
