in the do.. while loops lesson 10. the example code was -
var html = ' ' ; for ( var i =1; i <= 10000; i += 1 ) { html += '<div>' + i + '</div>'; } document.write(html);
is there no need of semi-colon after the (i += 1) ?

Treehouse TeacherIn short, no. A for loop should look like this:
for(i = 0; i < someNumber; i++) {
doSomeCode();
}
But, I'd suggest you go back and look at the example code again because what you've posted in the question won't run. A for loop always has three parts. The first part keeps track of the counter (in this case i). The second keeps track of how many times it should go through the loop. And the third part increments (or decrements) the counter.

3,174 PointsThanks Jennifer, that's just what i thought. it was just the third part of the loop that doesn't END with a semi-colon; that bothered me :)
BTW: how did you post an html comment ?

Treehouse TeacherThere's a nice little markdown cheatsheet link here on the forums that will explain how to post your code :) As a side note: that bothered me too when I was first learning, but it'll be second nature in no time!
