I'm doing the Practise Javascript Maths Methods video and Dave is again talking about using HTML tags in Javascript and I'm wondering if I've somehow missed a video introducing how to use HTML tags in Javascript. Does anyone know which video this is included in please? I've looked back over all the videos I've done so far in the Javascript Basics course and can't find anything anywhere.
Also, in this challenge he's mentioning using a linebreak tag - <br> - but again this has never been introduced to me in either the Javascript Basics, How to Make a Website or CSS Basics courses (I'm on the Front End Web Development track). I'm a complete novice when it comes to programming/scripting and felt like I was keeping up pretty well with everything so far, but I'm finding that the Javascript Basics course seems to be missing things out that should be included on a 'Basics course'.
Thank you in advance for any help/advice.

- I recommend that before taking the Practise Javascript Maths Methods course you should take at least the first part of the JavaScript Basics course ( https://teamtreehouse.com/library/javascript-basics course) to not overtake or confuse you. Frontend track is very gradual, and if you can follow it as it is patterned you will not have problems to understand. I recommend that before taking other courses you see the requirements well as they are well explained at the beginning.
- To understand how to manipulate the dom with javascript there is a very good course https://teamtreehouse.com/library/javascript-and-the-dom-2
- The <br> tag its a line break. Here some info https://www.w3schools.com/tags/tag_br.asp
Good luck!

You can't use HTML tags within JavaScript outside of strings, with the exception of JSX but that's a more complex topic which is not relevant to this challenge.
The document.write method was demonstrated during the first couple of video of the Basic JavaScript course, and HTML tags were used during those demonstrations.
As for the <br> tag I'm somewhat surprised that was not shown off during the "How to Make a Website" course as it is a pretty basic HTML tag. But there are a lot of HTML tags so running into one you are unfamiliar with is not something that is going to be a rarity when doing web development. And usually a short Google search will bring up a pretty good explanation of what the tag does. The <br> tag for example simply creates an empty line, which is useful for spacing content.
