Why do we need HTML tags in JavaScript?

Hey Yan,

Using HTML tags along with document.write() (and in other circumstances) allows you to push elements out to the page. The difference between using HTML elements in your methods and just using plain text is that with the HTML elements you'll have major control over the style and interactivity of the text. You can add an id/classes/other attributes to the text which can all enhance the text and also enhance the user experience.

If, however, you just use plain text such as "This text will show up, too!", you don't have nearly as much control over the text. And, especially when using document.write(), the text will all be scrunched together unless you write in some <br> elements or newline characters "\n". And it will always be in black ink on a white background when using document.write(). Using plain text is just plain boring :)

My understanding is that it 'writes' to the html document. That means the browser 'sees' what you add as html and takes the tags into consideration.. So if you left out the <p></p> the added text wouldn't be in it's own 'container'

You could have done <div> or <h1> or whatever you wanted the added text to be.

you see a lot more of this with Jquery where you are using a library of javascript functions designed to change things inside the hmtl document
