Yea, the structural typing nature of TS drives me nuts. One thing I like in TS is the ability to reference individual "parts of a type", for example Account["email"] instead of "string" in function signatures. Is there something like that in C#?

TS errors are my only real complaint about TS.

Otherwise it's a joy to work in, imo.

Trying to go from TS back to JS is a frustrating experience to say the least.
