❔ LINQ - I get confused by Where, Find, FindFirstValue etc.
I don't know what method works with certain Types.
If I make an array of string and use .Find it doesn't exist. If I make a List of string .Find will be there.
I understand that .Find is for lists but it's still confusing and there are other methods than .Find.
Is there some sort of cheat sheet somewhere that makes all this clearer?

different convention between List and array in terms of finding with
.Find
for arrays you'd need to do it like this Array.Find(myArray, Predicate<T>)
also, both List<T>.Find and Array.Find aren't linq.Array.Find(T[], Predicate) Method (System)
Searches for an element that matches the conditions defined by the specified predicate, and returns the first occurrence within the entire Array.
your cheat-sheet is Intellisense and docs.microsoft.com
That's a good thread to follow actually. I really would like to learn LINQ and how those methods work! I don't understand from YT tutorials.
