4,582 PointsSo these <>, </> are HTML tags. If he puts an <h1></h1>...<h6></h6>, it means he's writing a heading tag into the document. Javascript allows you to modify the state of the HTML document using something called the Document Object Model (DOM). This is slightly more advanced stuff and it's not necessary for you to know it to complete this course, at least that's what I think.
If you are curious, check out one of the HTML courses just to get a quick idea of what is going on in these videos. But the main focus is on conditional statements and Javascript concepts rather than the tags.

4,582 PointsWhen Dave writes
document.write("<p>That's right</p>");
it means that he is adding a paragraph to the document with the text, "That's right".

it is only Vital if he wants to get a message across they are not part of Java Script in any way, they are HTML tags and you use HTML to print messages to your page, <p> </p> stands for paragraph. <h> </h> stands for heading. a few basics courses in HTML will give you a good understanding.
