Notes : • DOMContentLoaded • it is triggered when all content is loaded ( before rendering with some excpetion) • • Normal Case • line by line execution • for script tag DOMContentLoaded will not wait • async and defer = async load • async Case • script tag loads independetly and executes independetly • DOMContentLoaded and async scripts don’t wait for each other: • • defer case • script tag loads independetly and executes when the DOM is ready • DOMContentLoaded event handler waits for the deferred script. It only triggers when the script is downloaded and executed. • • • #coding #javascript #async #defer #javascript • #html #script #DOM #AkshaySaini • @AkshaySaini • Please follow us • / dev.19.community • Thanks for watching us ... • Dev19🖤
