One of the things that developers loved about jQuery was its use of the $(document).ready() method.

This useful method allows you to run any JavaScript code and safely interact with any DOM element without worrying that the element doesn't exist. If you want to do this with vanilla JavaScript, you have a couple of options:

Listen for the DOMContentLoaded event on the window or document
Listen for the load event on the window

The DOMContentLoaded event fires as soon as the DOM is ready to be interacted with. So this is almost the equivalent of jQuery's $(document).ready().

The load event, on the other hand, fires when the page and all of its resources are finished loading. So this one could be useful in some circumstances, but more than likely the one you want is DOMContentLoaded.

For example, if you want to get the exact dimensions of an element on the page and the content hasn't finished loading, you won't get an accurate measurement. So the load event would be useful in that case.

I mentioned that DOMContentLoaded isn't exactly the same as jQuery's method. The jQuery docs explain the difference:

"jQuery's .ready() method differs in an important and useful way: If the DOM becomes ready and the browser fires DOMContentLoaded before the code calls .ready( handler ), the function handler will still be executed. In contrast, a DOMContentLoaded event listener added after the event fires is never executed."

Regarding this problem, MDN suggests the following:

"DOMContentLoaded may fire before your script has a chance to run, so it is wise to check before adding a listener."

Then they provide the following suggestion for your code:

if (d.readyState === 'loading') {

									  d.addEventListener('DOMContentLoaded', doSomething);

									} else {

									  doSomething();

									}

In this instance "d" is a variable that represents the document.

Notice that first the script uses the readyState property to check if the DOM is still loading. The 'loading' state is the one that occurs right before the 'interactive' state in the loading process. So the DOM is not yet loaded. Thus I can safely attach the event.

If the 'loading' state has already passed, the else branch goes directly to the stuff to load after the DOM is ready.

As you can see, as long as you understand exactly what the vanilla JavaScript events accomplish, then you shouldn't need to use jQuery at all, assuming you're not worried about browser bugs and inconsistencies, of course.
