The script Tag Mocktest

You can specify the version of JavaScript used in a <script> tag by using the type attribute with the appropriate MIME type. For example, type="text/javascript" specifies JavaScript version 1.0.

The language attribute in the <script> tag is used to specify the scripting language used in the script, such as JavaScript. It helps browsers identify and interpret the script correctly.

Inline JavaScript code always executes before external JavaScript files because the browser processes inline code as it encounters it during HTML parsing, before loading and executing external scripts.

The order of script execution is determined by the order in which the <script> tags appear in the HTML document. Scripts are executed sequentially based on their position in the document, starting from the top and moving down the document structure.

Using external JavaScript files instead of inline code reduces code redundancy and promotes code reusability, as the same script can be included and used across multiple HTML pages without duplicating the code.

The async attribute is used to include a JavaScript file asynchronously. Adding async to the <script> tag tells the browser to load the script asynchronously while parsing the HTML, improving page loading speed and allowing other resources to load in parallel.

The defer attribute in a <script> tag delays script execution until after the document is parsed. It ensures that scripts are executed in the order they appear in the document, maintaining their relative order and preventing delays in page rendering.

The src attribute in the <script> tag is used to specify the location (URL) of an external JavaScript file that should be included and executed in the HTML document.

The async attribute in the <script> tag is used to load the script asynchronously, allowing it to load and execute independently of other resources while the page continues to render. This can significantly improve page load performance.

The defer attribute in the <script> tag is beneficial when the script can be loaded asynchronously and executed after the document is parsed. This allows the HTML content to be fully loaded before script execution, improving page loading performance.
