What Is The Vanilla JavaScript Equivalent Of Jquery’s $.ready() Function To Call A Function When The Page/dom Is Ready For It?

In vanilla JavaScript, you can use the DOMContentLoaded event to achieve the equivalent of jQuery’s $.ready() function. Here’s an example of how to call a function when the page/DOM is ready:

document.addEventListener("DOMContentLoaded", function(){
  // Your code here

function myFunction() {
  // Your logic here

In the above example, the DOMContentLoaded event is fired when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading. The callback function inside addEventListener will be executed when this event occurs, allowing you to call your desired function.

Note: If you want to support older browsers, you can also use window.onload event instead of DOMContentLoaded. However, DOMContentLoaded is preferred as it fires earlier than window.onload and allows for a faster execution of your code.
