QuestionHow can I add code, like variables, or draw functions?Incognito samCommunity AnswerInside the tags, you can write regular JavaScript code that will be run when the page loads. To add a variable, simply do something like this: let x = 5; console.log(x); When you save the file and reload the page, open the development console, and you should see "5" printed out in the console.

QuestionHow do I add multiple pictures to JavaScript?Community AnswerTo add a picture inside the script tags (using javascript of course) you need to load an image from your computer. Ex) var image = new Image(); Be sure to use the value new Image(). The variable name can change. Then, source the image. Ex.) image.src = 'image_file_name_here.png'; The word image before .src should be the name of the previously declared variable containing the new image() value. Finally, draw the image. This requires some knowledge of how to manipulate the website canvas, which cannot be explained here as it is quite long. There are very good sources on the web explaining how to draw images and pictures.
