For handshorting JS writing essentially, and providing easier cross browers support handling mainly... it provide also a bind for such relative complex API as to handle AJAX ^^
With success, it have provided some extension as JQueryUI to handle layout effects...

It makes you easier to code saving your time and making simplier some things.
For example you have 3 Paragraphs and you'd like to change bgcolor and font-style for each of them:
<p>One</p>
<p>Two</p>
<p>Three</p>
So you'll have code like this in JavaScript:
<script>
let ps = document.getElementsByTagName('p');
for (let i=0; i<ps.length; i++) {
ps[i].style.background = 'red';
ps[i].style.fontStyle = 'italic';
}
</script>
And like this - in jQuery:
<script>
$('p').css({'background':'red', 'font-style':'italic'});
</script>
And one more line is in <head> to import jQuery support to your page scripts:
<script src="https://code.jquery.com/jquery-3.2.1.js"></script>
