jQuery

jQuery is a JavaScript library that helps with a whooole lotta stuff including 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
