JQuery is a framework for writing javascript tasks in a easier way. JQuery it is written in javascript. Also, I should mention that browsers parse only html and css files as also js scripts. Hence, all javascript frameworks (jQuery, AngularJS, etc) are written in javascript. They provide you the oportunity to write js code easier but under the hook they are all written in javascript.
Example:
Say we have the following input element
<input id="button1" type="button" value="clickMe"/>
Also say that we want when someone click on the button to have an alert box showing to the user a ‘Hello’ message.
Then the code in javascipt would be:
document.getElemementById("button1").addEventListener('click', function(){
alert("Hello");
});
Using JQuery the above would be written as follows:
$('#button1').click(function(){ alert("Hello"); });
Using JQuery makes things more clear.
As you can see all JQuery is, is JavaScript.
