Wondering about the broken <h2> tag

The code on the video assigned one variable with an opening <h2> tag and ended the statement with a semicolon. Now more variables are declared and assigned a string value, ending each statements with a semicolon. One thing I noticed is the last variable which has the closing </h2> tag. Why does the <h2> tags still work even though it is broken and each statements are ended with a semicolon?

The semicolons are not part of the constructed string.

The JavaScript statements end with a semicolon, but that is not part of the string that the statements are building. The string is not written into the document until it is complete.

Can anyone tell me where h2 tags were discussed previously? I don't remember it being discussed in any of the lessons. It seems pretty foreign to me...

The <h2> tags are HTML tags and are not included in this Full Stack Javascript course, at least on the course description. The <h2> tags are used to format the texts that appear on the webpage and Javascript codes can be written inside <h2> tags for formatting. Ideally, one should already have some background about HTML and CSS when studying Javascript as these languages work hand in hand. No worries though, HTML and CSS are pretty much simpler than Javascript :)
