increment

is it possible to use i++ instead of i+=1 ??

does javascript accept increments such as "++i" or "i++" ?

edit: so, do both pre and post increments exist in javascript?

Although it's hard to find concise documentation on this, you can see that both pre- and post-incrementation work by testing them out. Pop open your Chrome DevTools console and run something like this line by line.

test = 0 (returns 0)
test++ (returns 0)
test (returns 1)
++test (returns 2)
test (returns 2)

Yes, it is possible.

You can do...

number++;

and number will increment by 1

Yes it is certainly possible to use either i++ or i += 1. As far as i know you can also use ++i but the proper convention is i++. I hope this helped.
