How to call jQuery function with JavaScript function?

JavaScript is the core of any website, it adds functionalities to a website, make the overall website responsive. But in JavaScript, it is hard to select an element and add different functions like toggling an element, fade-in an element, and more.

Concatenating jQuery and JavaScript makes it easy to use the jQuery function in JavaScript function whenever needed, instead of calling them separately.

$(document).ready(function() {
   // Your jQuery code here
});

Alternatively, you can use the following syntax

$(function() {

});

Inside the document ready function, you can call any jQuery function that you want to execute. For example

$(document).ready(function() {
   $("#element").hide(); // This will hide the element with the ID "element"
});

You can also pass a parameter to the jQuery function, like this

$(document).ready(function() {
   $("#element").hide(1000); // This will hide the element with the ID "element" over a period of 1 second (1000 milliseconds)
});
