====== jQuery ======
jQuery is a JavaScript library that helps with a whooole lotta stuff including [[ajax|AJAX]].
It helps with DOM traversal, like getting elements by ID etc. alot easier and DOM manipulation like adding elements, inserting them in certain spots etc.
let form = $("#form");
or
$(entry).appendTo("#entryList");
It also does event handling like doing an action when a button is clicked or when the page is loaded.
$("#submitButton").click(function (event) {
or
$(document).ready(function () {
And it ofc it does AJAX alot easier than making it manually.
I already did AJAX in the AJAX thingy fahhhh cries and throws up
