RENDER BLOCKING JAVASCRIPT
• 3 Ways to Handle
• Use inline JavaScript
• Declaring a Script as Asynchronous
• Deferring a Script
• Async
• <script async src=“/js/app.js”></script>
• Browser starts download and executes as soon as download is finished with no regard to the order of the script tags
• Defer
• <script defer src=“/js/app.js”></script>
• Browser starts download, but holds off executing the script until the HTML has been completely parsed and the DOM
tree has been constructed.
