Is it ok to use a while loop?

For this challenge, my first instinct was to use a while loop. I got the same answer, but was wondering if that is considered wrong? or is it wrong from a professional point?

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

var count = 0;

while (count < 10) { 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>'; count += 1; }

document.write(html);

That's certainly legitimate code. The advantage a for loop gives is that the initialization, conditional, and increment are all together in one place. But there's no functional difference when all are coded properly for a while loop (as they are here).

For future reference, when posting code, always use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down: Or watch this video on code formatting.
