What are differences between $(document).ready and $(window).load?

$(document).ready();

$(document).ready(function() {
 /** Add your code here **/
            


/** Add your code here **/

 console.log("HTML Document is fully load. HTML, javaScript and CSS is fully loaded.");
});

JavaScript code written inside $(document).ready will be called when HTML Document is fully loaded. It means JavaScript code will be called just after HTML, JavaScript & CSS is fully loaded.



$(window).load();

$(window).load(function() { 
 /** Add your code here **/
            


/** Add your code here **/


 console.log("Web page fully Loaded. HTML, Javascript, CSS, Images, Iframes and objects are fully loaded.");
