Is there an easy way to convert jquery code to javascript? [closed]

Is there an easy way to convert jQuery code to regular javascript? I guess without having to access or understand the jQuery source code.

This will get you 90% of the way there ; )

window.$ = document.querySelectorAll.bind(document)

For Ajax, the Fetch API is now supported on the current version of every major browser. For $.ready(), DOMContentLoaded has near universal support. You Might Not Need jQuery gives equivalent native methods for other common jQuery functions.

Zepto offers similar functionality but weighs in at 10K zipped. There are custom Ajax builds for jQuery and Zepto as well as some micro frameworks, but jQuery/Zepto have solid support and 10KB is only ~1 second on a 56K modem.

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api (you would probably call this: normal JavaScript).

This can however be a pain for some things. (which is why libraries were invented in the first place).

Googling for "javascript DOM traversing/manipulation" should present you with plenty of helpful (and some less helpful) resources.

The articles on this website are pretty good: http://www.htmlgoodies.com/primers/jsp/

And as Nosredna points out in the comments: be sure to test in all browsers, because now jQuery won't be handling the inconsistencies for you.

Whether we like it or not, more and more developers are being introduced to the world of JavaScript through jQuery first. In many ways, these newcomers are the lucky ones. They have access to a plethora of new JavaScript APIs, which make the process of DOM traversal (something that many folks depend on jQuery for) considerably easier. Unfortunately, they don’t know about these APIs!

In this article, we’ll take a variety of common jQuery tasks, and convert them to both modern and legacy JavaScript.

I proposed it in a comment to OP, and after his suggestion, i publish it has an answer for everyone to refer to.

Also, Jeffrey Way mentioned about his inspiration witch seems to be a good primer for understanding : http://sharedfil.es/js-48hIfQE4XK.html

Has a teaser, this document comparison of jQuery to javascript :

$(document).ready(function() {
  // code…
});

document.addEventListener("DOMContentLoaded", function() {
  // code…
});

$("a").click(function() {
  // code…
})

[].forEach.call(document.querySelectorAll("a"), function(el) {
  el.addEventListener("click", function() {
    // code…
  });
});

You should take a look.

No, especially if:

understanding the examples of javascript solutions written in jQuery [is] hard.

JQuery and all the frameworks tend to make understanding the code easier. If that's difficult to understand, then vanilla javascript will be torture :)
