ManagedCode.MimeTypes/MimeHelper.cs:1
- This change from 'application/javascript' to 'text/javascript' for .mjs files may break existing applications that expect the application MIME type. Consider if this is an intentional breaking change or if backward compatibility should be maintained.

ManagedCode.MimeTypes/MimeHelper.cs:1
- [nitpick] The x_b and x_t entries have been moved to the end of the JSON file, which changes their ordering. Ensure this reordering doesn't affect any order-dependent logic or tests.

Creating a new char array for each line split is inefficient. Consider using a static readonly char array or string.Split overload that takes individual char parameters.
