I am trying to create an array of values using a for loop in JavaScript with multiple div id's with successive numbers (i.e. their values) denoting depth. The issue that I am running into is that I can't add the DOM element, i.e. 'text by ship here' successfully to the stage. I added // to show different sections where I am stuck. In particular, I believe I am stuck on the for loop part of the code below //Trying to create a div array here with id's q0, q1, q2, ..., q3 and have used different functions such as for div[0].setAttribute("id", "q0") to be able to connect it with the create.jsDOMElement to add this text to the stage. Any help would be extremely appreciated! My apologies in advance if the code is too long. I have tried to express it succinctly.

</html>I have been able to make some progress on this. I am now running into the issue with the numbers needing to appear relative to the pixel 0, 0 on the Canvas/screen now, i.e. see the word relative.
<h1> I have some text here, and I need the numbers to appear relative to the Canvas/screen. </h1>
