Workspace preview causes chrome to hang

Again, an issue where my code matches the solution code yet my result is different. In this case I have refactored the code to the below. which matches exactly to the solution code.

BUT when I click the eyeball to preview the code in the browser window, it causes all my treehouse tabs to hang. it doesn't look like I've created an infinite loop anywhere, but at this point, I'm not sure I'm doing anything right.

Any help is appreciated. Thanks!

var html = '';
var red;
var green;
var blue;
var rgbColor;

for (var i = 0; i < 10; i =+ 1) {
  red = Math.floor(Math.random() * 256 );
  green = Math.floor(Math.random() * 256 );
  blue = Math.floor(Math.random() * 256 );
  rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';
}
document.write(html);

lastly, I've run the downloaded solution code and it behaves the exact same way it's demo'd in the video.

Thanks!

Hey there,

Just a quick glance, it looks like you have the incrementing symbol backward for the variable in the for loop. You have =+ when it should be +=.
Give that a go and see if that solves it.

:) :dizzy:

P.S. I also added JavaScript declaration to the Markdown for the code so syntax highlighting is correct. :)

well....that's not at all embarassing.? Thank you for finding what I couldn't after having stared at it for an hour.
