Ajax Jquery and javascript

Somebody help me out. I do understand the theoretical difference among these languages but apparently their functionality is a bit a mystery. Couldn't they have kept improving one of them,just like we have HTML and html5 ?

AJAX = Asynchronous JavaScript And XML. AJAX is not a programming language. AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page. https://www.w3schools.com/xml/ajax_intro.asp jQuery is a JavaScript Library. jQuery greatly simplifies JavaScript programming. https://www.w3schools.com/jquery/ JavaScript is the programming language of HTML and the Web. It mostly renders dynamic content on the web.

Javascript has been around forever, and has been improved upon over the years. jQuery was something that someone else made that greatly simplified JS syntax and added easier functionality for things like AJAX. You can do Ajax by itself with vanilla JS, which is useful, or you can use the form of it that is built into jQuery. As you can see, it's much different than HTML, but they all play off one another so it's a good thing because the community is able to make things great instead of just one entity. Between all the above, I don't think I could ever go back to vanilla JS again. Between jQuery, AngularJS, and NodeJS, I would go nuts if I had to use vanilla. :D

jQuery is a library, meaning that it simply runs a JavaScript code which makes a whole lot of built-in functions, which you can then use in your own code.
