load javascript after dom ready code example

Example 1: JavaScript that executes after page load

//two ways of executing JS code after page is loaded, use "DOMContentLoaded" when able

document.addEventListener("DOMContentLoaded", function(){
    //dom is fully loaded, but maybe waiting on images & css files
});

window.addEventListener("load", function(){
    //everything is fully loaded, don't use me if you can use DOMContentLoaded
});

Example 2: document ready without jquery

document.addEventListener("DOMContentLoaded", function(event) { 
  //we ready baby
});

Example 3: wait for the dom to load javascript

document.addEventListener('DOMContentLoaded', (event) => {
  //the event occurred
})
