Why didnt we use <br> to break the html code?

Hi,

Can anyone explain to me why without the use of <br> in the html variable, the code manage to break itself nicely into each questions/parts ? To my knowledge, += adds on to existing value of an variable, so it must be a long string and needs <br> at some point? 

html = "You got " + correctAnswers + " question(s) right."
html += '<h2>You got these questions correct:</h2>';
html += buildList(correctGroup);
html += '<h2>You got these questions wrong:</h2>';
html += buildList(wrongGroup);
print(html);

this is because h tags, h1, h2 etc are block level elements by default

"Browsers typically display the block-level element with a newline both before and after the element"
