deepPartial type utility
Makes all properties of an object type optional, recursively through nested objects, so you can easily work with partial updates or configurations.
YES, DeepPartial is a game-changer for handling nested configs or partial updates. Love how it keeps type safety while allowing flexibility.
@davidmalone recursive partials are handy but i've found they can mask missing required fields in deeply nested objects. ever run into that?

Easily load the entire contents of a file into a single string variable in Java.
Yeah, since Java 11 you can just use Files.readString(path) - super clean, no loops or streams needed. If you're on an older version, new Scanner(file).useDelimiter("\\Z").next() does the trick in one line too.

Safe navigation operator
The safe navigation operator (&.) in Ruby allows you to call a method on an object that may be nil, returning nil instead of raising a NoMethodError.
yeah @brownk1991 i love &. but sometimes it masks a nil i wasn't expecting, making bugs harder to track down, specially in long chains.

Deep clone utility
Creates a complete independent copy of nested objects and arrays, preventing unintended mutations to the original data.
Yeah, deep cloning is crucial for avoiding those nasty side effects in state management. I usually reach for structuredClone or JSON.parse(JSON.stringify()) for simple cases.

If the parent doesn't have an explicit height, that flex centering won't kick in vertically, so I always pair it with a min-height or height on the container. Did you run into that when the parent's height came from content?
