Tips for structuring JavaScript code within ASP.NET MVC projects

We're looking to enhance the functionality of a view page with some Ajax functions. This means that when a user clicks on a delete or insert button, an Action will be triggered to carry out a CRUD operation in the background, followed by refreshing the items list once the task is completed.

In many instances, JavaScript code is typically embedded within the <script> tag directly on the view page. However, considering that multiple functions may be required for a single view (such as collecting form data, validating it, and then making an AJAX call), we are contemplating moving all these scripts into a separate .js file.

Regarding best practices, should we store these .js files in the same folder as their respective Views? Or would it be better to place them all in a centralized 'Script' folder and reference from there?

Furthermore, should each individual view have its own separate .js file, or would it be more efficient to combine all scripts for different views into a larger file?

Additionally, just like how C# code can be grouped using #region for organization, is there a similar feature in JavaScript to help manage lengthy scripts effectively?

We appreciate any advice you can provide on this matter. Thank you.

Instead of using the Scripts directory for this purpose, I prefer to utilize the Content directory. The Scripts directory typically contains all default JavaScript files such as jQuery and others, so I like to keep my own JavaScript (along with CSS and images) in the Content directory.

To organize your files, consider creating separate folders similar to how you structure your views (e.g. ~/Content/js/myviewfolder/somename.js).

If you want to better structure your JavaScript code, you can divide independent code into different files and then combine them into one file. Alternatively, group your code into anonymous self-executing blocks that can be collapsed. Personally, I recommend using different files and exploring methods to build them into a single file if necessary.
