What is this jQuery code doing? --> $("div").text()

Question

This is from the jQuery Module 5 quiz. The question asks what the output is after two clicks, which the answer is 111 and which I understand is the concatenation of strings of 1.

I know that $("div").text()+1 is converting the 1 in the div to string 1 and concatenating to 1, so the output is "11" for this section. My question is why is the first $("div").text needed?

Here is the quiz question below:

What will be the output after the div is clicked two times?
<div>1</div>

<script>
$("div").click(function() {
$("div").text($("div").text()+1);
});
</script>

Answer 1

It will add 1 to text of div and then replace the original text with the new text which is originaltext1

here $("div").text() is used to fetch the text inside div tag

Answer 2

$("div").text() us used here to get the text inside div

In first time it will return 1 which concat with 1 to set text inside div 11.
Second time it return 11 which concat with 1 to set div text 111.

selector.text();
Is use to get the value of text inside selected element

Selector.text("xyz");
Is used to set the value xyz in selected element.
