you can tell i vibecode this typescript because it looks like a slow descent into madness

oh shit maybe i shouldve been paying attention to the c# releases this has been a pain point for so damn long

$The field keyword The token field enables you to write a property accessor body without declaring an explicit backing field. The token field is replaced with a compiler synthesized backing field. For example, previously, if you wanted to ensure that a string property couldn't be set to null, you had to declare a backing field and implement both accessors: private string _msg; public string Message { get => _msg; set => _msg = value ?? throw new ArgumentNullException(nameof(value)); } You can now simplify your code to: public string Message { get; set => field = value ?? throw new ArgumentNullException(nameof(value)); }$

anyways here's the other project i've been posting about doing generalized personal task log & reminder system github.com/TechnoJo4/sc...

the scrobbly main interface with a little bit of example data. in order:
buttons for "inject EEn (4mg)" and "pay rent ($1000)", the latter colored blue
a list of active reminders, with one item: "you should pay rent (2 weeks ago)"
number input and buttons for 4 tasks: inject EEn, go outside, pay rent (again blue), buy stupid shit (this one colored red)
a table of two recent events
management links for buttons, reminders, quotas, tasks, units
