Q:

Displaying javascript variable without clearing screen

I am learning how to develop and I wanted to work on a simple "clicker" game using HTML5, CSS3, and JavaScript. I'm looking to practice creating something similar to Cookie Clicker. I have created three icons and they each serve a purpose. I would like to figure out how to display a modified variable on a portion of the screen without clearing the screen or having to resort to a window popup.
Here is the link to the project if anyone is interested in helping:

The function in question is the displayPoints function in the master.js file. I currently have the following:
function displayPoints() {
    confirm(numClicks);
}

This does what I want. It displays the correct number of clicks. If I click on the middle button twenty times and then click the "Display Points" button, it'll display the right number of points. However, it does it in a popup window. How can I display the number of points inside the browser without using a popup window?
I tried the following code:
function displayPoints() {
    document.write(numClicks);
}

This code worked inside the browser but it cleared the screen of the icons, so it's not possible to keep generating points by clicking on the second button. 
tl;dr - How can I update variables in real time, on the browser screen, without using a popup window and without clearing the screen? Any help would be much appreciated.

A:

You can use an html element on the page and fill it with data such as:
<span id="numClicksResult"></span>
<script>document.getElementById('numClicksResult').innerHtml=10;</script>
