javascript – Script Tag – async & defer
Async and Defer
Normally HTML page execution starts line by line. When an external JavaScript
<script>
element is encountered, HTML parsing is stopped until a JavaScript is download and ready for execution. This normal page execution can be changed using thedefer
andasync
attribute.Defer
When a defer attribute is used, JavaScript is downloaded parallelly with HTML parsing, but it will be execute only after full HTML parsing is done.
Async
When the async attribute is used, JavaScript is downloaded as soon as the script is encountered and after the download, it will be executed asynchronously (parallelly) along with HTML parsing.

<!DOCTYPE>
– Definition and UsageThe declaration must be the very first thing in your HTML document, before the tag.
The declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.
In HTML 4.01, the declaration refers to a DTD, because HTML 4.01 was based on SGML. The DTD specifies the rules for the markup language, so that the browsers render the content correctly.
HTML5 is not based on SGML, and therefore does not require a reference to a DTD.
Tip: Always add the declaration to your HTML documents, so that the browser knows what type of document to expect.
