Courses Plus Student 876 PointsWhen the browser starts it will go threw the index.html file. It sees that you have linked to a
<script src="script.js"></script>file and he will check that too.In the script.js file you have defined 3 variables which the browser keeps in mind. He kind of stores them. If you open your developer console in the browser (right click and inspect) you can check the variables. But first you need to tell the browser that you also want to see it in the console. You do that with console.log(variable);
So if you add at the bottom of your script.js the line
you will actually see what the browser has stored in the variables.... hope it helps.
