In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace. Using these new types may align well with how databases allow similar data to be represented. Specifically, these types align well with the SQL Server date and time data types. 

JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime.
