The document.write doesnt execute until the end I assume?

I initially wanted to give feedback for the score after each question. The document.write was not executing until after all the questions were answered. I assume thats normal and there is probably a better way to do that once I learn a little more? The code below worked great for one question. After I added a second is where I noticed the document.write not executing until all questions had been answered. It seemed to run all of them at the end, even though I had it in each question.

var totalCorrect = 0
var Q1 = prompt('What year was the USMC founded?');
if (parseInt(Q1) === 1775 ){
  totalCorrect += 1
document.write('<p>Correct! ' + 'You have answered ' + totalCorrect + ' correct so far</p>');
} else {
document.write('<p>Sorry. ' +  Q1 + ' was not correct.' +  'You have answered ' + totalCorrect + ' correct so far</p>');
}

I think the function actually does execute right away, but the rendering of the page is delayed until the script ends. Either way, it makes it unusable for immediate feedback during execution. But for an immediate display you can use "alert".

As you progress in your studies, you'll soon learn about event handlers and input controls which will give you much better tools for making your pages interactive.
