Typo in the solution?

I noticed the question was stated as this:

Complete the code below to create a for loop that executes 10 times, writing the value of the variable i to the document each time:

_______(var i = 0; i <________ ; i++) { document.write(i); }

Is "i++" written correctly or did they mean to type "i+=1"?

i++ is the same as i = i + 1.

This makes i go up by one every time the for loop runs until the boolean condition is false.

This is simply shorthand and by no means a typo.

Hi Joshua Harman. Thanks for pointing this out. Jacob Proffer is correct. i++ is the same as i += 1. However, I didn't demonstrate that in my course, so I can see how the question would be confusing. I've updated the question so that it now uses i += 1. Thanks!

Hey Dave, I'm not sure who else or where to ask this, but Is there an issue with the iTunes feeds?

Thanks for the info!!! SWEET! That's awesome!!
