TypeScript can figure the return type out by looking at the return statements, so we can also optionally leave this off in many cases
You really shouldn’t use arrow function as class members. Arrow functions are duplicated in memory for each class instance, while proper method members are written once in your class’s prototype and shared between all instances.
any means “ignore the type”,
unknown means “we don’t know the type”, which aren’t the same thing, and for better code you’d rather not know the type than ignore it.
You can’t use
unknown as a simple replacement for
any, that wouldn’t make sense.
unkwnown carries the implication that you should not use this variable other than passing it around. Or testing its type to get rid of the “unknown” state.
