In this example, the
src attribute within the script tag:
filename.js file will be included and executed.
However, there are also limitations to using script tags. One limitation is that the code included using script tags is loaded synchronously, meaning that the browser will pause parsing and rendering until the code is fully loaded and executed. This can potentially impact the page loading speed and user experience.
Another limitation is that including code using script tags requires an HTTP request for each external file, which can increase the page load time, especially if there are multiple external files.
External File References
<script> tag can be used with the
src attribute. The
There are several advantages to using external file references for code organization and maintenance.
Firstly, it promotes code reusability. By separating your code into different files, you can easily reuse the same code in multiple places without duplicating it. This not only reduces the amount of code you need to write but also makes it easier to update and maintain.
Secondly, it improves code organization. Having separate files for different functionalities or components allows you to have a clear structure and makes it easier to find and understand specific parts of the codebase.
Additionally, using external file references can enhance code maintenance. When you make changes to a specific functionality or component, you only need to modify the relevant file instead of searching for the code scattered throughout a single large file.
<script src="filename.js"></script> syntax provides a clean and modular approach to code organization and maintenance. It promotes code reusability, improves code organization, and simplifies code maintenance.
async attribute in the
Here's an example of using asynchronous loading:
<script async src="script.js"></script>
Here's an example of using deferred loading:
<script defer src="script.js"></script>
<script src="filename.js"></script> syntax, developers can keep related code in separate files and include them as needed. This not only enhances code modularity and reusability but also improves code maintenance.
