Just use .map and .get – there's no need for intermediate variables or loops
const liTexts =
$ ('#wa li')
.map ((idx,elem) => $(elem).text ())
.get ()
console.log (liTexts)
// [ 'one', 'two', 'three' ]<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="wa">
<li>one</li>
<li>two</li>
<li>three</li>
</ul>8 Comments

Man, other people are the worst, am I right? (Kidding. And I agree that
.map() is the way to go here.)
aaaaaa
for a second I thought you had
map's callback incorrect, before I checked jquery's documentation and realized their api is just backwards. Also, nice to meet you @nnnnnnnnnnnn
@aaaaaa - Likewise. I don't know, but I suspect it is backwards because you can use
this to refer to the element, so then if you want the index too you can just define that one argument in your callback.nnnnnn
@aaaaaa - 20%
this, 20% closures, 20% typos, 20% didn't read easily accessible documentation, 20% code this for me. (OK, I shouldn't have said 100%, there are good, non-duplicate questions too.)

var myArr = []; // define the array
$('#wa li').each(function (i) {
myArr.push($(this).text()); // push the value into the array
});
console.log(myArr); // ['hello', 'world', ...] use the array

You can use array.push() to the values to the array
var myArr = []; // define the array
$('#wa li').each(function (i) {
myArr.push($(this).text());
});
