Good question! So with jQuery you attach an event listener to the button which contains your ajax request.

$('button').click(function() {
   //...
   $.getJSON(/* ... */);
}

However with pure Javascript you have to edit this inside the HTML itself using the onclick event, then inside your JS use the new XMLHttpRequest() as shown in the previous video.

HTML

<button onclick="yourAjaxFunctionHere()">Click me</button>

JS

function yourAjaxFunctionHere() {
   var request = new XMLHttpRequest();
   //...
}

There's no need to edit the HTML file, you can add an event listener using the addEventListener method.
