For loop

Question

In the example given by Solo learn, they used "document.write(i + "<br/>)", however when I tried to use (i + "<br>") I've got the same answer. If those two are correct, why they use backslash?

Answer 1

Moshi

<br> is for HTML5
<br/> and <br /> are for XHTML
however the better way is written with and back slash, <br /> is always preferable

https://www.w3.org/TR/xhtml1/#C_2

So both are alternative ways to write tag and used for same purpose.

Answer 2

Thank you!
